Hardest ALEKS Subjects: Why Students Struggle and How to Get Through
Quick Answer
The hardest ALEKS subjects are Chemistry (especially General Chemistry), Statistics, Trigonometry, and Precalculus. These courses share common pain points: abstract reasoning that doesn’t feel like “normal math,” strict formatting requirements, and Knowledge Checks that can wipe out weeks of progress. If you’re struggling with one of these subjects, you’re not alone—and you’re not bad at math. These courses are genuinely difficult, and ALEKS’s adaptive system makes them feel even more punishing.

Why Some ALEKS Subjects Are Harder Than Others
Not all ALEKS courses are created equal. Some feel manageable—you can grind through topics, make steady progress, and finish with effort. Others feel like they’re actively working against you.
The hardest ALEKS subjects share common characteristics:
Abstract reasoning: Unlike algebra where you’re solving for X, subjects like trigonometry and statistics require you to think in unfamiliar ways. You’re not just calculating—you’re interpreting, visualizing, and applying concepts that don’t always feel intuitive.
Precision requirements: Chemistry and statistics punish small errors severely. Wrong significant figures, incorrect units, misremembered formulas—any of these can turn a correct approach into a wrong answer.
Cumulative complexity: These subjects build on themselves aggressively. Miss one foundational concept and you’ll struggle with every topic that follows. ALEKS’s adaptive system makes this worse by jumping between difficulty levels unpredictably.
Interface challenges: Some subjects require ALEKS’s more complex input tools—chemical notation with subscripts and superscripts, graphing for trigonometry, statistical tables and formulas. The interface itself becomes an obstacle.
ALEKS Difficulty Rankings
| Subject | Difficulty | Why It’s Hard |
|---|---|---|
| Chemistry | Very Hard | Notation nightmares, dimensional analysis, sig figs |
| Statistics | Very Hard | Probability rules, hypothesis testing, detail overload |
| Trigonometry | Hard | Non-linear thinking, identity memorization, graphing |
| Precalculus | Hard | Combines trig + advanced algebra, function analysis |
| Intermediate Algebra | Moderate | Builds complexity, but still “feels like math” |
| College Algebra | Easier | Foundational, straightforward problem-solving |
Chemistry: The Notation Nightmare
ALEKS Chemistry—both General Chemistry and Organic Chemistry—consistently ranks as the hardest subject on the platform. The reasons go beyond just “chemistry is hard.”
Input formatting is brutal: You need to enter chemical formulas with proper subscripts (H₂O), ionic charges (Ca²⁺), and sometimes draw Lewis structures. ALEKS’s chemistry input tools have a steep learning curve, and a formatting error counts as a wrong answer even if your chemistry is correct.
Dimensional analysis chains: Multi-step unit conversions are the backbone of chemistry. One wrong conversion factor and the entire problem cascades into a wrong answer. ALEKS doesn’t give partial credit.
Significant figures: Chemistry requires strict attention to sig figs. Answering “2.50” when ALEKS wants “2.5” (or vice versa) is marked wrong. This feels arbitrary and punishing.
Research consistently shows that general chemistry has among the highest failure rates of any college course. According to data from the American Chemical Society, introductory chemistry courses have historically had DFW rates (D grades, failures, and withdrawals) exceeding 30% at many institutions.

Statistics: Death by Details
Statistics might be the most deceptively difficult ALEKS subject. It doesn’t look like traditional math, which leads students to underestimate it—until they’re drowning.
Probability rules are counterintuitive: Human brains aren’t wired for probability. Concepts like conditional probability, Bayes’ theorem, and the difference between “and” vs “or” probabilities trip up even strong math students.
Hypothesis testing is a minefield: Null hypotheses, p-values, Type I and Type II errors, confidence intervals—each concept has specific rules that must be applied precisely. Mixing up “reject” vs “fail to reject” on one problem can cascade into confusion on every related topic.
Formula overload: Unlike algebra where you learn patterns, statistics requires memorizing (or correctly applying) dozens of specific formulas. Standard deviation, variance, z-scores, t-scores, chi-square—each has its own formula and use case.
The American Statistical Association has documented that statistics anxiety is a recognized phenomenon affecting student performance, distinct from general math anxiety.

Trigonometry: The Wall
Many students hit trigonometry and feel like they’ve suddenly become “bad at math.” This isn’t a reflection of ability—it’s a reflection of how different trig is from everything before it.
Non-linear thinking required: Algebra is largely linear: follow steps, get answers. Trigonometry requires visualizing circles, understanding periodic functions, and thinking in terms of angles and ratios. It’s a fundamentally different mode of mathematical reasoning.
Identity memorization: Trig identities (sin²θ + cos²θ = 1, double angle formulas, sum and difference formulas) must be memorized and applied correctly. Forgetting one identity can make entire problem sets unsolvable.
Graphing complexity: ALEKS trigonometry requires graphing sine, cosine, and tangent functions with correct amplitude, period, and phase shifts. The graphing interface adds another layer of difficulty.
Bearing word problems: Navigation and surveying problems using angles are notoriously confusing. “North of East” vs “East of North” trips up students constantly.

Precalculus: Everything at Once
Precalculus earns its difficulty by combining trigonometry with advanced algebra and throwing in new concepts like limits and function analysis. It’s essentially a greatest-hits compilation of hard math.
Trig + algebra combined: You need solid skills in both, but many students arrive with gaps in one or both areas. Those gaps become impossible to hide.
Function analysis: Understanding domain, range, asymptotes, end behavior, and transformations requires abstract thinking that many find challenging.
Preparation for calculus: The pressure of knowing this course is a gateway to calculus adds stress. Students who struggle here often worry they’ll never be able to handle higher math.
The Knowledge Check Trap
Difficulty is one thing. What makes hard ALEKS subjects feel truly punishing is the Knowledge Check system.
Here’s the trap: You grind for weeks, mastering topic after topic. Your pie grows. You feel like you’re making progress. Then a Knowledge Check hits, and ALEKS tests you on that one trig identity you learned three weeks ago and haven’t touched since.
You miss it. ALEKS decides you don’t actually know it. But because trig concepts are interconnected, failing that one topic can cascade—suddenly 5-10 “mastered” topics drop back into your learning queue.
This is especially brutal in hard subjects because:
- The concepts are harder to retain without regular practice
- Topics are more interconnected, so one failure affects many
- You’re already working harder than in easier subjects
The ALEKS system is designed to ensure mastery through periodic reassessment—but for students in difficult subjects, this design can feel like punishment for having a human memory.
The Emotional Toll: It’s Not Just You
If you’re feeling stressed, anxious, or demoralized by ALEKS, you’re experiencing something real and documented.
Math anxiety is physiological: Research published in journals like Frontiers in Psychology shows that math anxiety triggers genuine stress responses—elevated cortisol, increased heart rate, impaired working memory. You’re not being dramatic. Your body is responding to perceived threat.
ALEKS’s design amplifies pressure: The adaptive system, the unpredictable Knowledge Checks, the visible pie chart showing your progress (or lack thereof)—all of these create a high-stakes environment that can worsen anxiety.
Struggling doesn’t mean you’re stupid: The hardest ALEKS subjects are genuinely difficult. Millions of students struggle with chemistry, statistics, and trigonometry every year. Needing help isn’t a character flaw—it’s a rational response to a challenging situation.

How to Get Through Hard ALEKS Subjects
If you’re committed to pushing through yourself, here are strategies that help:
Front-load your hardest topics: Don’t save difficult concepts for the end when you’re exhausted and deadline pressure is highest. Attack them early when you have energy and time to struggle.
Review before Knowledge Checks: Spend time refreshing older topics, especially the foundational ones from weeks ago. This reduces the cascade effect when a check hits.
Use external resources: ALEKS’s built-in explanations aren’t always sufficient. Khan Academy, YouTube tutorials, and your textbook can provide alternative explanations that click better for your learning style.
Work in focused sessions: Marathon ALEKS sessions lead to diminishing returns and increased errors. Work for 45-60 minutes, take a break, return fresh.
Know when to get help: There’s no virtue in struggling alone to the point of failure. Tutoring, study groups, and professional services exist because these subjects are genuinely hard.
Frequently Asked Questions
What is the hardest ALEKS subject?
Chemistry (especially General Chemistry) and Statistics are consistently rated as the hardest ALEKS subjects. Chemistry combines complex notation requirements with precise calculations. Statistics requires counterintuitive probability reasoning and formula-heavy hypothesis testing. Both are significantly harder than algebra-based courses.
Is ALEKS harder than regular homework?
Many students find ALEKS harder than traditional homework because of its adaptive nature and Knowledge Checks. You can’t just complete assignments and move on—ALEKS continually retests you and can remove mastery you’ve already earned. The lack of partial credit also makes it less forgiving than many traditional courses.
Why do I keep losing progress on ALEKS?
Knowledge Checks periodically test your retention of previously mastered topics. If you miss questions on topics you completed weeks ago, ALEKS removes them from your mastered pie. This is especially common in hard subjects where concepts are easy to forget without regular practice. Learn more about why ALEKS resets progress.
Is ALEKS Statistics harder than ALEKS Math?
For most students, yes. Statistics requires a different type of thinking than algebra or even calculus. The probability concepts are counterintuitive, hypothesis testing has many precise rules, and the subject doesn’t “feel like math” to students who are comfortable with equation-solving.

Can I switch to an easier ALEKS course?
This depends on your program requirements. Some students can satisfy math requirements with College Algebra or Quantitative Reasoning instead of Statistics or Precalculus. Check with your advisor about which courses fulfill your degree requirements—you may have more flexibility than you realize. See our guide to easier ALEKS subjects.
Should I get help with hard ALEKS subjects?
If you’re struggling significantly, getting help is a rational choice. The hardest ALEKS subjects have high failure rates for a reason. Professional help can mean the difference between passing and failing, especially when you’re balancing other courses, work, or family obligations. Learn about our ALEKS services.
