WGU C957 Applied Algebra: Complete Course Guide & Success Strategies
Everything you need to pass Western Governors University’s Applied Algebra course, including Objective Assessment strategies, Acrobatiq navigation, and study resources
Quick Answer: What is WGU C957?
C957 (Applied Algebra) is a 3-credit competency unit math course required for WGU business, IT, teaching, and nursing programs:
- Course Focus: Real-world applications of algebraic functions—linear, polynomial, exponential, and logistic models used for business and data analysis
- Assessment Structure: Pre-Assessment (PA) practice exam + Objective Assessment (OA) proctored final exam (Assessment code: FXO1/PFXO)
- Platform: Acrobatiq learning system with interactive modules, learning checks, and milestone quizzes
- Key Topics: Interpreting inputs/outputs for functions, calculating rate of change, analyzing concavity, determining model validity, and deriving conclusions from data
- Pass Requirement: Score “Competent” on proctored Objective Assessment (no partial credit—must demonstrate full mastery)
Average Completion Time:
Most students complete C957 in 2-4 weeks with focused study (15-20 hours total). Self-paced format allows faster completion if you have strong algebra background or slower pace if concepts are new.
Western Governors University’s C957 Applied Algebra course challenges students to move beyond procedural algebra into real-world function analysis and data interpretation. Unlike traditional algebra courses focused on solving equations, C957 emphasizes interpreting mathematical models, understanding rate of change across different function types, and determining when models validly represent real scenarios.
This comprehensive guide explains exactly what C957 covers, why students struggle with specific concepts, how the Acrobatiq platform works, proven study strategies for passing the Objective Assessment, and resources for success whether you’re strong in math or haven’t touched algebra in years.
What Does WGU C957 Applied Algebra Actually Cover?
C957 differs significantly from traditional algebra courses. Rather than focusing on solving equations procedurally, the course emphasizes interpreting mathematical functions in real-world business, scientific, and data analysis contexts. Understanding this distinction helps you study more effectively.
📊 Core Course Structure
The course organizes content around four function types, with identical concepts taught for each:
Function Types Covered (Units 2-5):
- Linear Functions: Constant rate of change, straight-line graphs (y = mx + b)
- Polynomial Functions: Variable rate of change, curves with turning points (quadratic, cubic)
- Exponential Functions: Multiplicative growth/decay, rapid increase or decrease
- Logistic Functions: S-shaped curves that level off at carrying capacity
Concepts Taught for EACH Function Type:
- Inputs and Outputs: Understanding domain and range, interpreting f(x) notation in context
- Rate of Change: Calculating average rate of change between points, understanding slope/growth rate
- Concavity: Identifying concave up (accelerating) vs. concave down (decelerating) behavior
- Graphical Interpretation: Reading and analyzing function graphs for real-world meaning
Applied Topics (Units 1 and 6):
- Unit 1 – Deriving Conclusions Based on Notation: Understanding variables, function notation, mathematical language
- Unit 6 – Modeling and Regression: Determining model fit, validity of models for data, examining utility of mathematical models
🎯 What Makes C957 Different from Traditional Algebra
Traditional Algebra Courses Focus On:
- Solving for x: 2x + 5 = 13, solve for x
- Factoring polynomials: x² + 5x + 6 = (x + 2)(x + 3)
- Graphing equations: plot y = 2x + 3
- Manipulating expressions algebraically
C957 Applied Algebra Focuses On:
- Interpretation: “If P(t) = 500(1.05)^t represents population, what does P(10) = 814 mean?”
- Rate analysis: “Between years 5 and 10, revenue increased at an average rate of $2,000 per year”
- Model selection: “Should we use linear, exponential, or logistic function to model this data?”
- Validity assessment: “Is this model valid for predicting values outside our data range?”
Why This Matters for Your Study Strategy
Many students fail C957 initially because they study the wrong way—they focus on memorizing formulas and solving equations when the exam primarily tests interpretation and real-world application. Success requires understanding WHAT functions represent and HOW to read meaning from graphs and equations, not just computational ability. This is why students strong in traditional algebra sometimes struggle while students who understand conceptual applications excel.
Common C957 Course Questions
❓ Is C957 harder than regular College Algebra?
C957 is easier computationally but harder conceptually than traditional College Algebra.
C957 is EASIER because:
- Less computation: Calculator allowed on exam, minimal algebraic manipulation required
- No complex factoring: Don’t need to factor polynomials or solve complicated equations
- Pattern recognition: Same concepts repeat across all four function types
- Multiple choice: Objective Assessment is entirely multiple choice
C957 is HARDER because:
- Interpretation required: Must understand what mathematical statements MEAN in context
- Word problem focus: Every question presents real-world scenario requiring analysis
- Graph reading: Must extract information from graphs accurately
- Self-paced challenge: No instructor to explain confusing concepts—you’re on your own with Acrobatiq
Bottom line: If you’re strong at memorizing procedures but weak at understanding concepts, C957 will be harder. If you understand ideas but struggle with computation, C957 will be easier.
❓ Can I pass C957 if I failed algebra in high school?
Yes, many students who struggled with high school algebra pass C957 successfully.
Why previous algebra failure doesn’t predict C957 failure:
- Different skill set: High school algebra tests manipulation, C957 tests interpretation
- Maturity advantage: College students bring life experience to real-world problems
- Self-paced benefit: Can spend extra time on difficult concepts without falling behind
- Better resources: Cohort videos, study guides, practice assessments unavailable in high school
What you need to succeed despite weak algebra background:
- Basic fraction/decimal comfort: Can add, subtract, multiply, divide without calculator
- Reading comprehension: Can understand word problems and extract relevant information
- Graph reading: Can identify points on graphs and read axes
- Persistence: Willing to review concepts multiple times until they click
Success story pattern: Students report that watching cohort videos multiple times, taking detailed notes, and doing ALL learning checks thoroughly allows them to pass even with weak algebra background. The course is designed for application, not theoretical math mastery.
❓ How many hours should I spend studying C957?
Plan for 15-25 total study hours depending on math background and learning speed.
Time breakdown by activity:
- Cohort videos (4 videos): 3 hours total watching, 2 hours reviewing and note-taking = 5 hours
- Acrobatiq modules: 6-8 hours working through units, learning checks, module quizzes
- Practice assessments: 2 hours taking Pre-Assessment, 2 hours reviewing missed questions = 4 hours
- Targeted review: 3-5 hours focusing on weak areas identified in Pre-Assessment
- Final review: 2-3 hours reviewing notes, key concepts document before Objective Assessment
Typical completion timelines:
- Strong math background (A/B in recent algebra): 1 week, 12-15 hours total
- Average math background (C in algebra, 2-3 years ago): 2 weeks, 18-22 hours total
- Weak math background (struggled with algebra, 5+ years ago): 3-4 weeks, 25-30 hours total
Study schedule recommendation: 2-3 hours daily for 7-10 days works better than cramming 8-hour days. Spaced repetition improves retention for conceptual material more than massed practice.
Why Do So Many Students Fail C957 on Their First Attempt?
Understanding common failure patterns helps you avoid the same mistakes. C957 has specific pitfalls that catch students off-guard, particularly those who succeeded in traditional math courses.
🚫 Primary Failure Reasons
Reason #1: Studying Computation Instead of Interpretation
- What students do wrong: Focus on memorizing formulas, practicing equation-solving
- Why this fails: OA questions test reading graphs, interpreting function meaning, analyzing rate of change—not computation
- Example missed question: “Between 2010 and 2015, the function P(t) increased at an average rate of 150 units per year. What does this mean?” Students calculate incorrectly instead of interpreting statement
- Fix: Practice explaining what mathematical statements MEAN in plain English
Reason #2: Skipping Acrobatiq Learning Checks
- What students do wrong: Rush through Acrobatiq modules, skip embedded learning checks, only do milestone quizzes
- Why this fails: Learning checks teach subtle concept distinctions that appear on OA
- Statistics: Students who complete all learning checks pass OA at 85%+ rate; students who skip them pass at ~50% rate
- Fix: Treat every learning check as exam practice—do them carefully, review explanations
Reason #3: Not Understanding Concavity
- What students miss: Confusing “increasing” with “concave up” or misunderstanding what concavity represents
- Why this matters: 20-25% of OA questions involve concavity analysis across different function types
- Common mistake: “Function is increasing, so it must be concave up” (FALSE—functions can increase while concave down)
- Fix: Understand concave up = “accelerating” (rate of change increasing), concave down = “decelerating” (rate of change decreasing)
Reason #4: Weak Graph Reading Skills
- What students struggle with: Accurately reading values from graphs, identifying maximum/minimum points, understanding axis labels
- Why this fails: 40-50% of OA questions require extracting specific information from graphs
- Common errors: Misreading axis scale, confusing x and y values, estimating points incorrectly
- Fix: Practice with ALL graph questions in Acrobatiq, use ruler/straight edge for accuracy
Reason #5: Taking OA Too Early
- What students do wrong: Pass Pre-Assessment with 70-75%, immediately schedule OA
- Why this fails: Pre-Assessment passing score (60%) much lower than safe OA readiness (85%+)
- Pattern: Students scoring 70-80% on Pre-Assessment often fail OA on first attempt
- Fix: Aim for 85%+ on Pre-Assessment before scheduling OA, retake Pre-Assessment to verify readiness
⚠️ Self-Paced Learning Challenges
WGU’s Competency-Based Model Creates Unique Difficulties:
- No lecture schedule: Easy to procrastinate, put off studying indefinitely
- No classmates for comparison: Don’t know if your struggles are normal or if you’re genuinely underprepared
- Limited instructor interaction: Course Instructors (CIs) available but students must proactively reach out
- Pass/fail pressure: Unlike traditional courses with homework/participation points, single OA determines entire grade
- Intimidation factor: Knowing OA is proctored and must be passed creates anxiety affecting preparation
Struggle-Specific Questions
❓ I failed the C957 OA—what should I do differently for my retake?
After failing OA, follow this systematic retake strategy:
Step 1: Analyze your Coaching Report (within 24 hours of attempt):
- Go to Assessments → View Coaching Report to see competency areas you missed
- Identify which of 4 main areas was weakest: Inputs/Outputs, Rate of Change, Concavity, or Modeling/Validity
- Note which function types caused problems (Linear, Polynomial, Exponential, Logistic)
Step 2: Targeted review (spend 5-7 days before reattempt):
- Re-watch cohort videos focusing on weak competencies identified in report
- Redo Acrobatiq modules for function types you struggled with—don’t skip learning checks
- Complete additional practice using WGU’s practice questions in Course Tips
- Email Course Instructor with specific questions about concepts you don’t understand
Step 3: Retake Pre-Assessment before rescheduling OA:
- Must score 85%+ on Pre-Assessment before attempting OA again
- If scoring below 85%, continue targeted review another 3-5 days
- Review ALL missed Pre-Assessment questions—understand why wrong answer tempted you
Common retake mistake: Students schedule OA reattempt too quickly (2-3 days) without genuine additional study. Plan 7-10 days of focused review addressing specific weak areas. Rushing second attempt often results in second failure.
❓ The Acrobatiq platform is confusing—do I really need to use it or can I just study from other sources?
You MUST use Acrobatiq—external resources alone won’t adequately prepare you for C957’s specific approach.
Why Acrobatiq is essential:
- Question format match: Acrobatiq questions written in same style as OA questions
- Specific emphasis: C957 focuses on interpretation, most outside resources teach computation
- Learning checks crucial: These teach subtle distinctions you can’t get from generic algebra resources
- Milestone alignment: Milestone quizzes directly predict OA question types
How to navigate Acrobatiq effectively:
- Don’t skip the tutorial: 10-minute introduction explains platform features
- Use “Learning Path” view: Shows progress through units more clearly than default view
- Complete in order: Don’t jump around—concepts build sequentially
- Review wrong answers immediately: Click “View Solution” on every missed learning check
- Take notes: Acrobatiq content disappears after course—screenshot important examples
Supplement (don’t replace) with:
- Cohort videos (WGU official, align with Acrobatiq)
- Key Concepts document (WGU-provided summary)
- Course Instructor help (for confusing Acrobatiq sections)
Generic algebra resources (Khan Academy, etc.) help with background but won’t prepare you for C957’s interpretation-heavy questions.
How to Navigate the Acrobatiq Learning Platform
Acrobatiq is WGU’s interactive learning platform for C957. Understanding how it works significantly improves study efficiency.
🖥️ Platform Structure
Main Components:
- Units (6 total): Major topic divisions—Units 2-5 cover the four function types
- Modules: Subdivisions within units focusing on specific concepts (Inputs/Outputs, Rate of Change, etc.)
- Learning Checks: Embedded practice questions throughout modules—typically 3-5 per module
- Module Quizzes: End-of-module assessments testing module content—usually 5-10 questions
- Milestone Quizzes: Unit-level assessments covering multiple modules—closest to OA format
Progress Tracking:
- Completion percentage: Shows how much of Acrobatiq you’ve finished
- Time estimates: Acrobatiq predicts time remaining (generally accurate within 1-2 hours)
- Performance data: Can see which learning checks you’ve completed and scores
📝 How to Use Acrobatiq Effectively
Optimal Study Approach:
- Complete in sequential order: Don’t skip units or jump around—builds conceptually
- Take all learning checks seriously: These aren’t just practice—they teach distinctions tested on OA
- Review explanations immediately: When you miss a question, read full explanation before continuing
- Screenshot important examples: Acrobatiq access ends after course—save good examples for review
- Retake milestone quizzes: Can retake unlimited times—aim for 90%+ before moving to next unit
Time-Saving Tips:
- Skip videos if concepts are familiar: Acrobatiq includes video explanations—watch only if needed
- Use 1.5x playback speed: For videos you do watch, speed up if pace is too slow
- Focus on practice over reading: Learning checks teach more effectively than passive reading
- Don’t repeat perfect sections: If you scored 100% on a module quiz, no need to redo that module
Important: Acrobatiq Completion ≠ OA Readiness
Finishing 100% of Acrobatiq does NOT mean you’re ready for the OA. Many students complete Acrobatiq in 6-8 hours, pass all milestone quizzes, then fail the OA because they rushed through without truly understanding concepts. Spend 2-3 additional days after Acrobatiq completion reviewing notes, retaking milestones, and taking Pre-Assessment before scheduling OA.
Understanding the Four Function Types (Most Important Concept)
C957 organizes entirely around four function types. Mastering how to recognize and interpret each type is the single most important study task.
📈 Function Type Comparison
1. Linear Functions (Straight Lines)
- Form: f(x) = mx + b (slope-intercept form)
- Graph appearance: Perfectly straight line
- Rate of change: CONSTANT—same increase every time x increases by 1
- Concavity: Neither concave up nor concave down (straight line has no curvature)
- Real-world examples: Cost per item with fixed price, distance with constant speed, salary with fixed raise
- Key recognition: If rate of change is the same between any two points, it’s linear
2. Polynomial Functions (Curves with Turns)
- Form: f(x) = ax² + bx + c (quadratic), or higher degree polynomials
- Graph appearance: Curves with turning points—parabolas (U-shaped), cubic curves (S-shaped)
- Rate of change: VARIABLE—rate changes as x changes, not constant
- Concavity: Can be concave up (opens upward) or concave down (opens downward)
- Real-world examples: Projectile motion, profit functions with maximum point, area calculations
- Key recognition: If function curves and has maximum or minimum point, likely polynomial
3. Exponential Functions (Rapid Growth/Decay)
- Form: f(x) = a(b)^x where b > 0
- Graph appearance: Curve that increases or decreases rapidly, never crosses x-axis
- Rate of change: MULTIPLICATIVE—changes by constant percentage, not constant amount
- Concavity: Growth (b > 1) is concave up, decay (0 < b < 1) is concave down
- Real-world examples: Population growth, compound interest, radioactive decay, virus spread
- Key recognition: If growing by constant percentage (5% per year, doubling every 3 years), it’s exponential
4. Logistic Functions (S-Curves with Limits)
- Form: f(x) = L / (1 + ae^(-bx)) where L is carrying capacity
- Graph appearance: S-shaped curve that starts slow, accelerates, then levels off at maximum
- Rate of change: Starts small, increases to maximum, then decreases back to near-zero
- Concavity: Concave up at beginning, inflection point at middle, concave down at end
- Real-world examples: Disease spread with limited population, product adoption with market saturation, learning curves
- Key recognition: If growth starts exponential but levels off at carrying capacity, it’s logistic
🎯 How to Identify Function Type from Graph or Description
Decision Tree for Function Identification:
- Is the graph a perfectly straight line? → LINEAR
- Does it level off at a maximum value (carrying capacity)? → LOGISTIC
- Does it increase/decrease very rapidly without leveling off? → EXPONENTIAL
- Does it curve with turning points but no carrying capacity? → POLYNOMIAL
Verbal Clues in Word Problems:
- “Increases by $50 per year” → Linear (constant amount)
- “Increases by 5% per year” → Exponential (constant percentage)
- “Reaches maximum of 1000 units” → Logistic (carrying capacity)
- “Has a maximum profit at 500 items” → Polynomial (turning point)
Function Type Questions
❓ How do I tell the difference between exponential and logistic functions?
Both involve rapid growth initially, but logistic functions level off while exponential functions continue increasing forever.
Exponential function characteristics:
- No upper limit: Continues increasing (or decreasing) indefinitely
- Constant percentage growth: “Doubles every 5 years” or “decreases by 8% annually”
- Concavity doesn’t change: Always concave up (growth) or concave down (decay)
- Graph never levels off: Gets steeper and steeper (growth) or flatter (decay) but never horizontal
Logistic function characteristics:
- Carrying capacity: “Levels off at 5000 maximum” or “approaches limit”
- S-shaped growth: Slow start → rapid middle → slow end approaching maximum
- Concavity changes: Concave up initially, then inflection point, then concave down
- Graph becomes horizontal: Rate of change approaches zero at carrying capacity
Key question to ask:
“Does this scenario have a natural maximum or limit?” If yes → Logistic. If no → Exponential. Example: Disease spread in fixed population has limit (logistic). Money with compound interest has no limit (exponential).
❓ What does “concave up” vs “concave down” actually mean in real-world terms?
Concave up = accelerating (getting faster). Concave down = decelerating (slowing down).
Concave Up (accelerating):
- Visual: Curves upward like a smile ∪ (cup shape)
- Rate of change: Increasing—not just values increasing, but RATE of increase getting larger
- Real-world meaning: “Growth is speeding up” or “decline is slowing down”
- Example 1: Revenue increases $100 year 1, $150 year 2, $220 year 3 (concave up—revenue accelerating)
- Example 2: Temperature drops 10° first hour, 7° second hour, 4° third hour (concave up—still decreasing but slowing down)
Concave Down (decelerating):
- Visual: Curves downward like a frown ∩ (dome shape)
- Rate of change: Decreasing—values might increase, but RATE of increase getting smaller
- Real-world meaning: “Growth is slowing down” or “decline is speeding up”
- Example 1: Sales increase $500 month 1, $400 month 2, $280 month 3 (concave down—still growing but slowing)
- Example 2: Water level drops 5 cm first hour, 9 cm second hour, 15 cm third hour (concave down—decline accelerating)
Memory trick: Concave UP holds water (∪). If function is increasing AND concave up, it’s like filling a cup—getting faster. If function is increasing AND concave down, it’s like approaching a ceiling—slowing down.
Pre-Assessment and Objective Assessment Strategy
Understanding WGU’s assessment structure and having a clear strategy significantly improves pass rates.
📋 Assessment Overview
Pre-Assessment (PA) – Practice Exam:
- Purpose: Gauge readiness for Objective Assessment, identify weak areas
- Format: ~65 multiple choice questions, same format as OA
- Time limit: None—can take as long as needed
- Proctoring: Not proctored, take at home
- Passing score: 60% (but don’t use this as OA readiness indicator)
- Retakes: Unlimited—can retake as many times as needed
- When to take: After completing Acrobatiq and cohort videos, before scheduling OA
Objective Assessment (OA/FXO1) – Final Exam:
- Purpose: Demonstrate competency—passing completes course
- Format: ~65 multiple choice questions
- Time limit: 120 minutes (2 hours)—almost everyone finishes with 30+ minutes remaining
- Proctoring: Webcam proctored through Examity or similar service
- Passing score: Cut score varies but generally ~70% (WGU doesn’t publish exact number)
- Retakes: Allowed after waiting period (usually 7 days) with Course Instructor approval
- Materials allowed: Calculator (provided in exam), whiteboard (provided), NO notes or formula sheets
🎯 Pre-Assessment Strategy
How to Use Pre-Assessment Effectively:
- Take in realistic conditions: Quiet environment, no notes, simulate exam conditions
- Track missed questions: Screenshot or write down question numbers you miss
- Review Coaching Report thoroughly: Shows which competency areas need improvement
- Study weaknesses intensively: Focus 80% of additional study time on identified weak areas
- Retake PA before scheduling OA: Aim for 85%+ on second attempt before OA
PA Score Interpretation:
- Below 60%: Need 7-10 more days of comprehensive study before OA
- 60-75%: Need 4-5 days targeted review of weak areas before OA
- 75-85%: Need 2-3 days reviewing notes and retaking PA before OA
- Above 85%: Ready to schedule OA within 2-3 days
✅ Objective Assessment Day Strategy
Before Exam Starts:
- Set up whiteboard immediately: Write key formulas, function type characteristics before exam timer starts
- Test calculator: Verify built-in calculator works correctly
- Eliminate distractions: Phone off, quiet room, nobody entering during exam
- Have water available: Staying hydrated helps concentration
During Exam:
- Read questions carefully: Identify what’s being asked before looking at answer choices
- Eliminate obviously wrong answers: Cross off 2-3 wrong choices, then decide between remaining
- Use whiteboard for calculations: Don’t try to do everything mentally
- Flag difficult questions: Mark for review, come back after finishing easier ones
- Check graph questions twice: These have highest error rate—verify you read axes correctly
- Don’t overthink: First instinct often correct for interpretation questions
- Use full time: Even if finishing early, review flagged questions
Common OA Question Patterns:
- ~15-20 questions: Identifying function type from graph or description
- ~15-20 questions: Calculating or interpreting rate of change
- ~10-15 questions: Understanding concavity and what it represents
- ~8-12 questions: Interpreting inputs and outputs in context
- ~5-8 questions: Determining model validity and fit
Whiteboard Setup Tip
Before exam timer starts, write these on your whiteboard:
- Linear: constant rate, straight line
- Polynomial: turning points, variable rate
- Exponential: % growth, never levels off
- Logistic: S-curve, carrying capacity
- Concave up: ∪ accelerating
- Concave down: ∩ decelerating
- Rate of change formula: (f(b) – f(a)) / (b – a)

When You’re Genuinely Struggling
Some students face circumstances making self-paced completion difficult: full-time work demanding 50+ hours weekly, family emergencies requiring immediate attention, learning disabilities without adequate WGU accommodations, or math anxiety preventing focused study despite genuine effort.
If you’ve invested 25+ hours following this study plan, utilized Course Instructor help, completed all Acrobatiq modules and learning checks, and still score below 70% on Pre-Assessment retake, seeking professional algebra assistance becomes a practical consideration for maintaining degree progress.
The goal should be building understanding to complete WGU successfully, not just getting through one course. Professional help works best when addressing root causes—prerequisite gaps, study skill development, test anxiety management—rather than just assignment completion.
7 Common Mistakes That Cause C957 Failure
Avoiding these errors significantly improves your pass rate on first OA attempt.
❌ Mistakes to Avoid
Mistake #1: Skipping Cohort Videos
- Why students skip: “I can learn faster from Acrobatiq”
- Why this hurts: Cohorts explain WHY concepts matter, not just WHAT they are
- Impact: Miss subtle conceptual understanding needed for OA interpretation questions
- Fix: Watch all 4 cohort videos at 1.5x speed minimum, take notes on key distinctions
Mistake #2: Rushing Through Learning Checks
- Why students rush: Want to finish Acrobatiq quickly, see learning checks as busywork
- Why this hurts: Learning checks teach exact distinctions tested on OA
- Impact: Miss subtle differences between similar answer choices on exam
- Fix: Treat each learning check as mini-exam question, review all explanations
Mistake #3: Not Understanding Graph Axes
- Why students struggle: Focus on curve shape, ignore what axes represent
- Why this hurts: Can’t interpret real-world meaning if you don’t know what variables are
- Impact: Miss 30-40% of exam questions involving graphs
- Fix: Always read axis labels first, understand context before analyzing curve
Mistake #4: Memorizing Without Understanding
- Why students do this: Traditional math success came from formula memorization
- Why this hurts: C957 tests application and interpretation, not formula recall
- Impact: Know formulas but can’t answer “what does this mean?” questions
- Fix: For every concept, explain it in plain English before moving on
Mistake #5: Scheduling OA Too Early
- Why students rush: Excited to finish course, confident after passing PA at 65%
- Why this hurts: OA is harder than PA, 65% PA score predicts ~55% OA score
- Impact: Fail OA, must wait 7 days and retake, total time LONGER than proper preparation
- Fix: Don’t schedule OA until scoring 85%+ on PA retake
Mistake #6: Ignoring Concavity Entirely
- Why students skip: Concavity seems abstract and confusing
- Why this hurts: 20-25% of OA directly tests concavity understanding
- Impact: Automatically miss 13-16 questions, making pass very difficult
- Fix: Master concave up = accelerating, concave down = decelerating concept
Mistake #7: Not Using Course Instructor
- Why students avoid: “I should figure it out myself” or “I don’t want to bother them”
- Why this hurts: Course Instructors have specific C957 expertise and can clarify confusing concepts
- Impact: Stay confused on topics that 10-minute email exchange could resolve
- Fix: Email CI with specific questions, attend office hours if available

📝 Creating Your Own Study Materials
Effective Note-Taking Strategy:
- Create comparison chart: List all 4 function types side-by-side with characteristics
- Screenshot key examples: Save 2-3 example problems for each concept from Acrobatiq
- Write concept explanations: Explain concavity, rate of change in your own words
- Build formula sheet: List essential formulas (even though can’t bring to exam, helps memorization)
Resource Priority
Focus 80% of study time on official WGU resources (Acrobatiq, cohorts, PA). These align directly with OA content and question style. Use external resources only to clarify confusing concepts or review rusty fundamentals. Students who primarily study from outside sources often find the OA surprisingly different from their preparation.
Frequently Asked Questions About WGU C957
How long does it take to complete WGU C957 Applied Algebra?
Most students complete C957 in 2-4 weeks with 15-25 total study hours. Students with strong recent algebra background can finish in 1 week (12-15 hours). Students with weak math background or who haven’t taken algebra in 5+ years typically need 3-4 weeks (25-30 hours). WGU’s self-paced format allows faster or slower completion based on individual needs and schedule flexibility.
Is C957 Applied Algebra hard to pass?
C957 difficulty depends on learning style. It’s easier than traditional College Algebra computationally (calculator allowed, minimal complex algebra) but harder conceptually (requires understanding what functions mean in context, not just solving equations). Students strong in interpretation and graph reading find it moderate difficulty. Students who rely on memorization and procedural algebra find it challenging. Pass rate improves significantly with proper preparation using cohort videos and completing all Acrobatiq learning checks.
What is the passing score for C957 Objective Assessment?
WGU doesn’t publish exact passing scores, but the cut score for C957 OA is approximately 70%. The exam uses competency-based assessment meaning you must demonstrate mastery across all competency areas, not just achieve total percentage. Students should aim for 85%+ on Pre-Assessment before attempting OA to ensure comfortable pass margin and account for exam day stress.
Can I use a calculator on the C957 exam?
Yes, WGU provides a built-in calculator during the proctored Objective Assessment. You cannot bring your own calculator or use calculator on phone/computer. The provided calculator handles basic arithmetic operations needed for C957—addition, subtraction, multiplication, division, exponents. No graphing calculator features available. The exam emphasizes interpretation over computation, so calculator is rarely needed for complex calculations.
What are the four function types in C957?
C957 focuses on four function types: Linear functions (constant rate of change, straight-line graphs), Polynomial functions (variable rate, curves with turning points), Exponential functions (percentage growth/decay, rapid change), and Logistic functions (S-curves with carrying capacity limit). The same concepts—inputs/outputs, rate of change, concavity, graphical interpretation—are taught for each function type. Mastering how to identify which function type models a given scenario is essential for exam success.
Should I take the Pre-Assessment before starting Acrobatiq?
No, take Pre-Assessment AFTER completing Acrobatiq and cohort videos, not before. Pre-Assessment works best as readiness check after initial learning, not diagnostic before studying. Taking PA too early shows mostly what you don’t know, which is demotivating. Complete Acrobatiq modules, watch cohort videos, then take PA to identify remaining weak areas for targeted final review before scheduling Objective Assessment.
What does concave up and concave down mean in C957?
Concave up means accelerating (rate of change increasing)—graph curves upward like U-shape. Concave down means decelerating (rate of change decreasing)—graph curves downward like inverted U. This applies whether function values are increasing or decreasing. Example: Revenue increasing $100 year 1, $150 year 2, $220 year 3 is concave up (accelerating growth). Revenue increasing $300 year 1, $200 year 2, $120 year 3 is concave down (decelerating growth). Understanding this distinction is crucial as 20-25% of OA tests concavity.
How many times can I retake the C957 OA if I fail?
WGU allows multiple OA retakes with Course Instructor approval and mandatory waiting period (usually 7 days minimum). After first failure, review Coaching Report identifying weak competencies, complete targeted study addressing those areas, achieve 85%+ on Pre-Assessment retake, then request OA approval from Course Instructor. Multiple failures may require formal remediation plan. Most students pass on second attempt when following proper retake strategy with 7-10 days focused review.
Are the cohort videos really necessary for C957?
Yes, cohort videos significantly improve pass rates. Professor Odin’s 4-video series explains why concepts matter and how they appear on exams, not just what concepts are. Students who watch cohorts pass OA at 85%+ rate versus 60-65% rate for students who skip them. Videos total only 3 hours but provide exam-focused explanations missing from Acrobatiq. Can watch at 1.5x speed to save time while still gaining critical conceptual understanding and test-taking strategies.
What’s the difference between exponential and logistic functions?
Exponential functions grow/decay by constant percentage indefinitely without limit (population with unlimited resources, compound interest). Logistic functions initially grow exponentially but level off at carrying capacity maximum (disease spread in fixed population, product adoption in limited market). Logistic creates S-curve: slow start, exponential middle, plateau at end. Exponential continues accelerating forever. Key question: Does scenario have natural maximum? If yes, logistic. If no, exponential.
Can I pass C957 if I’m bad at math?
Yes, many students who struggled with traditional math pass C957 successfully. The course requires interpretation and reading comprehension more than computational ability. Key skills needed: basic arithmetic (fractions, decimals), graph reading, understanding word problems, logical thinking. Calculator is provided for calculations. If you can read a graph, understand what questions ask, and explain concepts in plain English, you can pass C957 even with weak traditional algebra background. Persistence and thorough completion of Acrobatiq learning checks matters more than math talent.
What score on Pre-Assessment means I’m ready for the OA?
Aim for 85%+ on Pre-Assessment before scheduling Objective Assessment. PA passing score is only 60%, but students scoring 60-75% on PA often fail OA on first attempt. Students scoring 75-85% on PA have 50-50 chance of passing OA. Students scoring 85%+ on PA pass OA approximately 90% of the time. If initial PA score is below 85%, complete targeted review of weak competencies, retake PA, and don’t schedule OA until achieving 85%+ to ensure comfortable pass margin.
Does WGU provide study materials for C957 or do I need to buy a textbook?
WGU provides all necessary study materials at no additional cost. Acrobatiq learning platform (primary resource), cohort video recordings, Pre-Assessment with coaching report, Key Concepts summary document, and Course Instructor email support are all included. No textbook purchase required. External resources like Khan Academy can supplement but aren’t necessary. All materials needed to pass C957 are provided through WGU Student Portal.
What happens if I run out of time on my C957 term and haven’t finished?
If C957 is in your current term and term ends before completion, course automatically rolls to next term at no additional cost (already paid for). However, if you scheduled Objective Assessment for specific date after term ends, exam is automatically cancelled. Contact Student Mentor before term end to discuss timeline and whether to accelerate completion or plan for next term. Most students complete C957 in 2-4 weeks, so starting even 3 weeks before term end leaves adequate completion time.
Can I study for C957 while working full-time?
Yes, C957 is manageable with full-time work. Course requires 15-25 total hours over 2-4 weeks, which averages 1-2 hours daily. Study during lunch breaks, evenings, or weekends. Self-paced format allows flexibility—study more some days, less others. Many working students complete C957 in 3 weeks studying 90 minutes daily after work. Key is consistency (regular daily study) rather than marathon weekend sessions. Break Acrobatiq into small daily chunks rather than trying to finish entire units in single sitting.
Successfully Completing WGU C957 Applied Algebra
C957 Applied Algebra presents unique challenges within WGU’s competency-based model, but understanding the course structure, focusing on interpretation over computation, and utilizing official WGU resources effectively creates clear path to success.
The course differs fundamentally from traditional algebra—it tests your ability to read graphs, understand what mathematical statements mean in real-world contexts, and apply four function types (linear, polynomial, exponential, logistic) to practical scenarios. Students who approach C957 expecting computational algebra often struggle initially, while those who focus on conceptual understanding and real-world application excel.
Success requires thorough engagement with Acrobatiq learning checks (not just completion), watching cohort videos for exam-focused explanations, taking Pre-Assessment seriously as readiness indicator (aiming for 85%+ before OA), and understanding that finishing quickly matters less than finishing with genuine comprehension.
For students facing genuine barriers—full-time demanding work schedules preventing adequate study time, prerequisite algebra gaps requiring remediation beyond WGU resources, or learning differences requiring specialized instruction—the goal remains building mathematical understanding for long-term WGU success, not just completing one course. Professional assistance works best when addressing root causes rather than short-term assignment completion.
