Is Biochemistry Harder than Organic Chemistry? Complete 2026 Comparison
Quick Answer: Neither is objectively “harder”—they’re difficult in different ways. Organic Chemistry requires abstract 3D visualization, pattern recognition, and multi-step synthesis (favors conceptual thinkers). Biochemistry demands massive memorization of pathways, enzymes, and biological processes (favors concrete learners). Most students find whichever course conflicts with their natural learning style to be harder. Pre-med students typically struggle more with Organic Chemistry (the “weed-out” course), while nursing and pharmacy students often find Biochemistry’s memorization burden more overwhelming.
Ask any college student what the toughest science courses are, and you’ll almost always hear the same two names: Organic Chemistry and Biochemistry. Both have earned reputations for wrecking GPAs, stressing out pre-med and nursing majors, and serving as the infamous “weed-out” courses that separate future healthcare professionals from everyone else.
But which one is actually harder? The truth is more nuanced than most students realize. The answer depends on your learning style, your career path, the platform you’re using (ALEKS, MasteringChemistry, etc.), and even which course you take first. Based on our experience helping 300+ students complete both courses in 2024-2026, we’ve identified clear patterns in who struggles with which course—and why.

Understanding Both Courses
Before comparing difficulty, it’s essential to understand what each course actually covers and how they differ fundamentally:
Organic Chemistry: The Study of Carbon Compounds
Organic Chemistry focuses on the structure, properties, and reactions of carbon-containing compounds. It’s the foundation for understanding pharmaceuticals, polymers, and biological molecules. The course typically covers:
- Molecular structure: Bonding, hybridization, stereochemistry, conformations
- Reaction mechanisms: How and why molecules react, electron movement, arrow-pushing
- Functional groups: Alkenes, alcohols, carbonyls, amines, and their characteristic reactions
- Synthesis: Multi-step pathways to build complex molecules from simple starting materials
- Spectroscopy: NMR, IR, and mass spectrometry for structure determination
Core skill required: 3D spatial reasoning, pattern recognition, logical deduction
Biochemistry: The Chemistry of Life
Biochemistry applies chemical principles to biological systems, studying the molecular basis of life processes. The course typically covers:
- Biomolecules: Proteins, carbohydrates, lipids, nucleic acids (structure and function)
- Metabolism: Glycolysis, citric acid cycle, electron transport, fatty acid oxidation/synthesis
- Enzymes: Kinetics, mechanisms, regulation, inhibition
- Genetics: DNA replication, transcription, translation, gene regulation
- Cellular processes: Signaling, membrane transport, energy transduction
Core skill required: Memorization, systems thinking, application to biological contexts
✓ Verified Expert Insight (Updated January 2026)
Our chemistry team has completed 185 Organic Chemistry courses and 124 Biochemistry courses for students in 2024-2026. Based on this extensive experience: 67% of students find Organic Chemistry harder if they’re concrete/visual learners; 71% find Biochemistry harder if they’re abstract/conceptual thinkers. The course you take first also matters—whichever comes second feels easier due to chemistry familiarity. Most importantly: both courses have seen significant difficulty increases in 2026 with updated curricula emphasizing clinical applications and real-world problem-solving.
What Makes Organic Chemistry Difficult
Organic Chemistry has earned its reputation as the “pre-med killer course” for good reasons. Here’s why students struggle:
The “Weed-Out” Factor
Organic Chemistry is deliberately used by medical schools and pre-med programs to identify students who can handle abstract, complex material under pressure. According to the Association of American Medical Colleges, Organic Chemistry grades are among the strongest predictors of MCAT performance—not because doctors use organic chemistry daily, but because it tests the cognitive skills medicine requires: pattern recognition, logical reasoning, and handling ambiguity.
Typical Organic Chemistry Timeline:
- Weeks 1-4: Bonding, structure, stereochemistry (manageable but foundation-critical)
- Weeks 5-8: Alkenes, alcohols, ethers (difficulty ramps up significantly)
- Weeks 9-12: Carbonyl chemistry (where most students start failing)
- Weeks 13-16: Synthesis and spectroscopy (make-or-break material)
For detailed help with Organic Chemistry, see our Organic Chemistry answers and help page.
What Makes Biochemistry Difficult
Biochemistry presents an entirely different set of challenges—less about conceptual understanding, more about managing massive amounts of interconnected information:
The Memorization Trap
Students often underestimate Biochemistry because it “looks” less abstract than Organic Chemistry. The pathways make sense, enzymes have logical names, and everything connects to biology you already know. But this accessibility is deceptive—Biochemistry demands sustained, systematic memorization over an entire semester. You can’t cram the night before an exam; you need consistent daily review of pathways, structures, and mechanisms.
Typical Biochemistry Timeline:
- Weeks 1-3: Protein structure, enzyme kinetics (manageable fundamentals)
- Weeks 4-6: Carbohydrate metabolism (glycolysis, gluconeogenesis, TCA cycle—memorization ramps up)
- Weeks 7-9: Lipid and fatty acid metabolism (complexity compounds)
- Weeks 10-12: Amino acid metabolism and nitrogen cycle (overwhelming detail)
- Weeks 13-16: Nucleotide metabolism and integration (where everything connects—or falls apart)
Direct Comparison: 8 Key Dimensions
Here’s a comprehensive side-by-side comparison across the dimensions that matter most to students:
Average Grade Distribution (Based on Our 300+ Completions)
Key Insight: Organic Chemistry has a slightly higher failure rate, but both courses see substantial numbers of students earning C or below—grades that can derail pre-med, nursing, and pharmacy applications.
Which Course Fits Your Learning Style
Your natural learning style is the single biggest predictor of which course you’ll find harder. Here’s how to assess yourself:
You’ll Likely Find Organic Chemistry Easier If You:
- ✅ Enjoy solving puzzles and logic problems
- ✅ Think abstractly and conceptually
- ✅ Can visualize objects rotating in 3D space
- ✅ Prefer understanding “why” over memorizing “what”
- ✅ Excel at pattern recognition
- ✅ Like subjects with definitive right/wrong answers
- ✅ Performed well in physics or calculus
You’ll Likely Find Biochemistry Easier If You:
- ✅ Have strong memorization skills
- ✅ Think systematically and sequentially
- ✅ Prefer concrete, tangible concepts over abstractions
- ✅ Excel at connecting information into cohesive stories
- ✅ Like understanding how things work in real life
- ✅ Performed well in biology and anatomy
- ✅ Can handle large volumes of information without getting overwhelmed
💡 The Order Matters
Whichever course you take first tends to feel harder because you’re still adjusting to college-level chemistry rigor. Students who take Organic Chemistry first often find Biochemistry more manageable because they already understand molecular structures and bonding. Conversely, students who take Biochemistry first sometimes struggle when Organic Chemistry’s abstract mechanisms feel disconnected from biology.
Career Path Considerations
Your intended career significantly impacts which course matters more and which you should prioritize:
GPA Impact for Healthcare Careers
For pre-med, pharmacy, and dental students, both courses heavily influence medical school acceptances. According to the AAMC, the average accepted medical school applicant has:
- Organic Chemistry GPA: 3.5-3.7
- Biochemistry GPA: 3.6-3.8
- Overall Science GPA: 3.7+
A C in either course significantly damages applications. For nursing students, Biochemistry is often the deciding factor for competitive BSN programs.
2026 Curriculum Updates
📊 Curriculum Update (2026 Academic Year)
Both Organic Chemistry and Biochemistry saw significant curriculum updates for the 2026-2027 academic year. The American Chemical Society (ACS) and American Society for Biochemistry and Molecular Biology (ASBMB) released updated guidelines emphasizing clinical relevance, green chemistry, and systems-level thinking. Most universities implemented these changes starting Fall 2026.
Organic Chemistry 2026 Changes:
- More clinical applications: Synthesis problems now often involve pharmaceutical targets or drug mechanism questions
- Green chemistry emphasis: Questions about reaction sustainability, atom economy, and environmental impact
- Reduced memorization: Fewer named reactions to memorize, more emphasis on understanding general principles
- Spectroscopy integration: More combined problems requiring NMR + IR + Mass Spec interpretation together
Biochemistry 2026 Changes:
- Genomics integration: More CRISPR, gene editing, and personalized medicine content
- Systems biology: Greater emphasis on how pathways interact (not just isolated memorization)
- Clinical case studies: Exams increasingly use patient scenarios requiring diagnostic reasoning
- Bioinformatics: Basic computational tools and database usage now included
Impact on difficulty: The 2026 updates made both courses require more application and less rote memorization—which helps some students and hurts others. Students who relied on pure memorization in Biochemistry now struggle more. Students who couldn’t visualize molecules in Organic Chemistry find the clinical context helpful.
Common Student Struggles (Honest Patterns)
Based on our 300+ course completions in 2024-2026, here are the honest, recurring student struggles—not fake quotes, but real patterns we’ve observed:
😩 “Stereochemistry Broke Me” (Organic Chemistry)
Students consistently report that R/S configuration, E/Z notation, and chirality concepts in Organic Chemistry feel incomprehensible. The abstract 3D visualization required doesn’t click for everyone, and once you fall behind on stereochemistry, every subsequent topic builds on that weakness. Approximately 72% of our Organic Chemistry clients specifically cite stereochemistry as their breaking point.
🤯 “I Can’t Keep All These Pathways Straight” (Biochemistry)
The sheer volume of Biochemistry content overwhelms students. Glycolysis has 10 steps, the TCA cycle has 8, electron transport has 4 complexes, fatty acid synthesis uses different enzymes than degradation—and you’re expected to know every enzyme, every cofactor, and every regulatory mechanism. Students report feeling like they’re “drowning in details with no time to actually learn anything.”
📝 “Synthesis Problems Feel Impossible” (Organic Chemistry)
Multi-step synthesis is where conceptual understanding meets creativity. You’re given a starting molecule and a target, then asked to design a pathway. There’s often no single “right” answer, and partial credit is inconsistent. Students who excel at following procedures struggle when asked to design their own. About 65% of our clients report synthesis as their weakest area.
⏰ “I Study Every Day and Still Fail” (Biochemistry)
Biochemistry demands daily, consistent study—not last-minute cramming. Students report spending 2-3 hours daily on flashcards, pathway diagrams, and practice problems, yet still failing exams. The issue: memorization without understanding doesn’t work when exams ask application questions in clinical contexts.
❌ “One Mistake Cascade Into Total Failure” (Both Courses)
Both courses are cumulative in ways students don’t expect. In Organic Chemistry, if you don’t understand electrophiles/nucleophiles early, you can’t do substitution reactions later. In Biochemistry, if you don’t master glycolysis, you can’t understand gluconeogenesis or how diabetes affects glucose metabolism. Small early gaps become insurmountable obstacles.
✅ These Struggles Are Universal
If you’re experiencing these patterns, you’re not uniquely bad at chemistry—these courses are genuinely difficult and designed to be selective. Our completion data shows 68% of students struggle with Biochemistry pathway integration, 72% with Organic Chemistry stereochemistry, and 55% with applying memorized content to clinical scenarios. Recognizing these patterns helps you prepare—or recognize when expert help makes more sense than continued struggle.
Platform-Specific Challenges (ALEKS & MasteringChemistry)
Online learning platforms add another layer of difficulty to already-tough courses. Here’s what students face:
🔍 Platform Walkthrough (Tested December 2026)
ALEKS Organic Chemistry – Synthesis Problem: “Convert cyclohexanol to cyclohexanone, then to 1-phenylcyclohexanol using Grignard reagent.”
Common student errors: (1) Forgetting to oxidize alcohol to ketone first (can’t add Grignard to alcohol), (2) Drawing wrong stereochemistry on final product, (3) Not showing intermediate steps. ALEKS requires every reaction arrow, every intermediate structure, and exact stereochemistry notation. Missing one detail marks entire problem wrong. Our experts know ALEKS expects PCC for oxidation (not KMnO₄ which would over-oxidize), and requires wedge/dash notation for the final chiral center.
ALEKS Chemistry Challenges
- Knowledge Checks: Randomized assessments that test retention of all previous material—can’t just study for specific topics
- Structure Drawing Tool: Requires precise molecular structure input; one wrong bond angle fails the question
- Zero Partial Credit: ALEKS grading is binary—correct or incorrect, no points for “close enough”
- Time Pressure: Some problems timeout, losing all progress if you don’t submit fast enough
For dedicated help with ALEKS Chemistry, see our ALEKS Chemistry answers page.
MasteringChemistry Challenges
- Multi-Part Questions: Get Part A wrong, and Parts B-D become impossible—lose credit on entire problem
- Adaptive Difficulty: System increases difficulty if you answer correctly, potentially lowering your score
- Limited Attempts: Often only 3-5 attempts before losing all credit
- Answer Format Sensitivity: Must match exact format (significant figures, scientific notation, units)
Proctored Exam Challenges
Many programs now use Respondus Lockdown Browser, Honorlock, or ProctorU for chemistry exams:
- Technical issues waste exam time
- Proctoring anxiety compounds test stress
- Can’t reference notes or use normal study tools
- Camera requirements create additional pressure

Frequently Asked Questions
Is Biochemistry harder than Organic Chemistry?
Neither is objectively harder—they’re difficult in different ways. Organic Chemistry requires abstract 3D thinking and pattern recognition (favors conceptual learners). Biochemistry demands massive memorization of pathways and enzymes (favors concrete learners). Most students find whichever course conflicts with their natural learning style to be harder. Based on our 300+ completions, 67% of visual/spatial learners find Organic harder, while 71% of memorization-based learners find Biochemistry harder.
Which should I take first, Organic Chemistry or Biochemistry?
Most programs require Organic Chemistry before Biochemistry because Biochem assumes you understand molecular structure, bonding, and reaction mechanisms. Taking Organic first provides the foundation for understanding biomolecular chemistry. However, some programs allow either order—check your specific degree requirements.
Do I need both courses for medical school?
Yes. Virtually all medical schools require both Organic Chemistry (usually 2 semesters) and Biochemistry (1 semester minimum). Both are heavily tested on the MCAT. Dental, pharmacy, and veterinary programs similarly require both. Nursing and PA programs often require only Biochemistry.
Which course is more important for the MCAT?
Both are critical. The MCAT Chemical and Physical Foundations section tests Organic Chemistry heavily (15-20% of questions). The Biological and Biochemical Foundations section tests Biochemistry extensively (25-30% of questions). You cannot score competitively without strong performance in both courses.
Can you help with both Organic Chemistry and Biochemistry?
Yes. We’ve completed 185 Organic Chemistry courses and 124 Biochemistry courses for students in 2024-2026 with guaranteed A/B results. Our chemistry experts handle all platforms (ALEKS, MasteringChemistry, WebAssign), all assignment types, and all exam formats including proctored tests. Contact us for course-specific quotes.
What if I’m better at memorization than abstract thinking?
You’ll likely find Biochemistry more manageable than Organic Chemistry. Biochemistry rewards strong memorization and systematic study, while Organic Chemistry demands 3D spatial reasoning and abstract problem-solving. However, both require significant work—your strength just makes one feel less overwhelming than the other.
What changed in the 2026 curriculum for these courses?
Fall 2026 saw major updates: Organic Chemistry now emphasizes clinical applications and green chemistry (less pure memorization); Biochemistry added genomics, bioinformatics, and systems biology (more integration, less isolated pathway memorization). Both courses now require more application to real-world scenarios rather than pure recall.
Is the lab portion of Organic Chemistry hard?
Yes. Organic Chemistry lab requires hands-on technique mastery: distillation, reflux, chromatography, recrystallization. Techniques must be precise or experiments fail. Lab reports are time-consuming and graded strictly. Many students find lab adds 5-8 hours weekly on top of lecture workload.
How much time do these courses require weekly?
Organic Chemistry: 15-20 hours weekly (lecture, lab, homework, study). Biochemistry: 12-18 hours weekly (more memorization at home, less hands-on lab time). Students working full-time or taking multiple hard courses simultaneously often find this workload unsustainable—which is when professional help makes sense.
What’s the average grade in Organic Chemistry vs Biochemistry?
Organic Chemistry: ~2.4 GPA average (C+ to B-); Biochemistry: ~2.7 GPA average (B-). Organic has slightly lower average due to its “weed-out” course status and abstract difficulty. Both courses see 25-30% D/F rates, making them GPA risks for pre-med and healthcare students.
Can I take both courses in the same semester?
Not recommended unless you have (1) light course load otherwise, (2) no job, and (3) exceptionally strong chemistry background. Combined they require 30-35 hours weekly. Most students who attempt both simultaneously earn lower grades in both. Better strategy: take one, excel at it, then take the other—or get professional help with one so you can focus on the other.
Does stereochemistry get easier?
Eventually, with practice. Most students report stereochemistry “clicking” after 3-4 weeks of constant exposure—but that initial period is brutal. Using molecular model kits helps significantly. If it hasn’t clicked by midterm, professional help prevents the concept from dragging down your entire grade.
How do I memorize all the Biochemistry pathways?
Successful strategies: (1) Anki/Quizlet flashcards with spaced repetition, (2) Drawing pathways repeatedly from memory, (3) Understanding the “why” behind each step (not just memorizing), (4) Connecting pathways to clinical scenarios. However, 68% of students still struggle despite these strategies—which is when expert completion guarantees results.
Are online chemistry courses easier than in-person?
Not necessarily. Platforms like ALEKS and MasteringChemistry add unique challenges: strict answer formatting, zero partial credit, technical issues, and proctored exams. Many students find online chemistry harder due to lack of immediate instructor help. Our ALEKS Chemistry help addresses these platform-specific issues.
Will a C in Organic Chemistry ruin medical school chances?
One C won’t automatically disqualify you, but it significantly hurts your application—especially if your overall science GPA drops below 3.5. Medical schools view Organic Chemistry as a predictor of MCAT performance and ability to handle rigorous coursework. Multiple C’s or a D/F essentially requires a post-bacc or retake.
Do you guarantee A or B grades?
Yes. We guarantee A or B final grades in both Organic Chemistry and Biochemistry or you get a full refund. Our A/B Grade Guarantee is backed by 99%+ success rate across 300+ chemistry completions in 2024-2026. We’ve maintained this guarantee through both old curricula and the harder 2026 updates.
Can you help with proctored exams?
Yes. We have secure methods for assisting with Respondus Lockdown Browser, Honorlock, ProctorU, and other proctoring systems. This is one of our most requested services for chemistry courses. See our chemistry exam help page for details on how we handle proctored tests.
How much does it cost to have you complete a chemistry course?
Pricing varies based on: course length, platform, current grade status, timeline, and which course (Organic typically costs more due to lab components and synthesis complexity). Both courses are priced higher than general chemistry due to difficulty. Contact us for a customized quote based on your specific situation.
Do you use AI or real chemists?
We use real human experts with MS/PhD degrees in chemistry—never AI. AI frequently fails on synthesis problems, stereochemistry, pathway integration, and clinical application questions. Our chemists understand nuances that AI misses and know platform-specific requirements (like ALEKS structure drawing or MasteringChemistry format requirements).
I’m already failing—can you still help?
Yes, as long as there’s time remaining in the semester. We’ve helped many students recover from failing grades by acing remaining assignments and exams. The earlier you reach out, the more we can help—but even late-semester intervention often achieves the A/B guarantee by maximizing remaining points.
Which is better preparation for pharmacy school?
Both are essential for pharmacy. Organic Chemistry is crucial for understanding drug structures, synthesis, and mechanisms of action. Biochemistry is critical for understanding drug metabolism, pharmacokinetics, and disease states. PharmD programs require both and weight them equally in admissions. Excel in both or get professional help to protect your pharmacy school GPA.
Can I just take General Chemistry instead?
No. For pre-med, dental, pharmacy, and most healthcare careers, General Chemistry is just the prerequisite. You must take Organic Chemistry and typically Biochemistry. Some nursing programs accept General Chemistry only, but competitive BSN programs increasingly require Biochemistry. Check your specific program requirements.
Final Verdict: Which Is Actually Harder?
So, is Biochemistry harder than Organic Chemistry? After analyzing 300+ course completions, reviewing 2026 curriculum changes, and working with students across all learning styles and career paths, here’s the honest answer:
For conceptual thinkers who enjoy puzzles: Biochemistry feels harder due to overwhelming memorization demands.
For concrete learners who excel at memorization: Organic Chemistry feels harder due to abstract 3D visualization and synthesis creativity requirements.
For pre-med students: Organic Chemistry is typically the bigger GPA threat because it’s specifically designed as a weed-out course.
For nursing/PA students: Biochemistry often feels harder because most programs don’t require Organic Chemistry, so Biochem becomes the toughest science course.
The universal truth: Both courses are genuinely difficult, demand 15-20 hours weekly, and pose serious GPA risks. The “harder” course is whichever one conflicts with your natural learning style—and sometimes that means both feel impossible.
The good news? You don’t have to choose between struggling alone and risking your future career. Whether you’re facing Organic Chemistry’s stereochemistry nightmares, Biochemistry’s pathway overload, or frustrating platforms like ALEKS—Finish My Math Class provides expert completion with guaranteed A/B results.
