Overview
The MCAT is widely considered one of the most demanding standardized tests in the world. A perfect score is 528; the median score for students accepted to MD programs is approximately 511–512. The exam tests four areas: Biological and Biochemical Foundations, Chemical and Physical Foundations, Psychological/Social/Biological Foundations of Behavior, and Critical Analysis and Reasoning Skills (CARS). Serious prep takes 3–6 months of dedicated daily studying.
Exam format
| Section | Questions | Time | Covers |
|---|---|---|---|
| Chemical & Physical Foundations of Biological Systems (C/P) | 59 | 95 min | Physics, general chemistry, organic chemistry, biochemistry — passage-based and discrete questions |
| Critical Analysis and Reasoning Skills (CARS) | 53 | 90 min | Humanities and social science passages — NO outside science knowledge needed; pure reading comprehension and inference |
| Biological & Biochemical Foundations of Living Systems (B/B) | 59 | 95 min | Biology, biochemistry, organic chemistry — the heaviest content section |
| Psychological, Social, & Biological Foundations (P/S) | 59 | 95 min | Psychology, sociology, biology — high memorization of theories, researchers, and social phenomena |
Scoring
- Total: Each section 118–132. Total 472–528. Average for successful MD applicants: ~511–512
- Percentiles: 500 = 51st · 508 = 75th · 514 = 91st · 518 = 97th · 524+ = 99th+
- Note: A balanced score across all 4 sections is better than an extreme high in one and low in another. Many medical schools have section minimums (often 124+).
Study plan
-
Months 1–2: Content Review
- Review all MCAT-tested sciences with a content review book
- Make flashcards as you go — don't passive-read, actively test yourself
- Start CARS practice immediately: 1 passage per day minimum
-
Months 3–4: Question Practice
- Switch from content review to question practice: 50–100 questions/day
- Use AAMC Question Packs for the most accurate difficulty calibration
- Start P/S memorization: all major psychology theories and social phenomena
-
Month 5: Full-Length Practice Tests
- Take 1 full-length practice test per week (on Saturdays, matching your real test day)
- Complete all AAMC full-lengths (6 total)
- Intensive error analysis: understand WHY every wrong answer is wrong
-
Month 6: Final Polishing
- Targeted content review based on your weakest test areas
- Final 2 AAMC practice tests
- Reduce study intensity the final week — protect mental energy
Strategies
CARS
- Read every passage START to FINISH before answering — never skip to questions first
- Track the author's tone and main argument as you read
- "According to the passage" questions: the answer is literally in the text — don't use outside knowledge
- Practice CARS every single day — it is a skill that takes months to develop, not days
B/B & C/P
- Passage-based questions: usually the answer is either in the passage OR from your content knowledge — distinguish which
- Biochemistry pathways (glycolysis, Krebs, amino acid synthesis): know them cold
- For physics: master the equation relationships, not just the formulas
- Discrete questions are often high-yield content knowledge — never skip them to focus only on passages
P/S
- Build a master list of every theorist and their key contribution (Freud, Erikson, Piaget, Vygotsky, etc.)
- Sociology vocabulary (stratification, prejudice, discrimination, institutional racism) is heavily tested
- Many P/S questions can be answered by careful passage reading even without memorized content
Common mistakes
- Treating CARS like a science section — no outside knowledge, only the passage
- Only reading content review books without doing practice questions — active retrieval is non-negotiable
- Skipping full-length practice tests — stamina for 7+ hours is a real skill that must be trained
- Not using official AAMC materials — third-party tests are notably less accurate than AAMC
- Starting too late — 3 months minimum, 6 months ideal for competitive scores
How Quizard helps with the MCAT
- Upload your MCAT content review chapters and generate targeted MCQ drills per section
- Create P/S flashcard decks with all psychology/sociology theories, researchers, and definitions
- CARS passage-reading practice: upload humanities and social science texts for reading comprehension questions
- Spaced repetition system ensures biochemistry pathways and physics equations are permanently memorized
- Daily challenge mode: 30 questions/day across mixed sections to maintain consistent science review
Recommended resources
- AAMC Official MCAT Materials (the most accurate prep available)
- Kaplan MCAT Complete 7-Book Series (comprehensive content review)
- Princeton Review MCAT Subject Review Books
- Anking Anki Flashcard Deck (free, comprehensive MCAT flashcard system)
- Jack Westin CARS Practice (daily free CARS passages)
Frequently asked questions
What MCAT score do I need for medical school?
Most MD programs want 510+. Top schools (Harvard, Johns Hopkins, Mayo) average 520+. DO programs are generally more flexible (504–510 range for many programs).
How many times can I take the MCAT?
Up to 3 times per year, 4 times in two years, and 7 times total lifetime. Medical schools see all attempts, so multiple takes require showing significant improvement.
Should I use Anki for MCAT prep?
Yes — spaced repetition is highly effective for MCAT content memorization, especially P/S and biochemistry. The pre-made AnKing deck covers nearly all testable content.
Is the MCAT harder than the GRE?
They test different things. The MCAT requires mastery of 4 full university-level science courses plus 7+ hours of sustained mental performance. Most students find the MCAT significantly more demanding.
