1. What is the MCAT?

The MCAT (Medical College Admission Test) is the standardized exam required for admission to virtually all MD and DO medical schools in the United States and Canada. It is administered by the AAMC (Association of American Medical Colleges).

Unlike the GRE or GMAT, the MCAT is heavily science-based. It tests foundational knowledge in biology, biochemistry, chemistry, physics, and psychology, alongside critical thinking and scientific reasoning. It is one of the most demanding standardized exams in graduate education, both in length and content depth.

No GRE alternative. Unlike law schools (which accept the GRE) or business schools (which accept both GMAT and GRE), no MD-granting medical school in the US accepts anything other than the MCAT. There is no path around it.


2. Format and sections

The MCAT has four sections, each scored independently. The exam runs 6 hours and 15 minutes of actual testing time, with administrative procedures and breaks bringing the total test day to approximately 7.5 hours. See the official AAMC section overview for full details.

SectionQuestionsTimeScore range
Chemical and Physical Foundations of Biological Systems5995 min118–132
Critical Analysis and Reasoning Skills (CARS)5390 min118–132
Biological and Biochemical Foundations of Living Systems5995 min118–132
Psychological, Social, and Biological Foundations of Behavior5995 min118–132

Total: 230 questions. Total score: 472–528. The exam includes two optional 10-minute breaks and one optional 30-minute mid-exam break.

What each section tests

  • Chem/Phys: General chemistry, organic chemistry, biochemistry, and physics, all applied to biological and medical contexts. Heavy on equations and quantitative reasoning.
  • CARS: The only section with no science content. Passages from humanities and social sciences; tests reading comprehension and critical analysis. No outside knowledge needed, only what's in the passage. Often the most challenging section for science-focused students.
  • Bio/Biochem: Biology, biochemistry, and organic chemistry. The most content-heavy section. Covers molecular biology, genetics, metabolism, and physiology.
  • Psych/Soc: Psychology, sociology, and biology of behavior. Tests understanding of how social and psychological factors affect health, a reflection of modern medical school curricula.

For non-native English speakers: CARS is the section that most surprises international students. It requires fast, precise reading of dense academic passages in English, with no science knowledge to fall back on. Budget dedicated CARS practice time separately from your science content review. Daily reading of complex English texts (academic journals, long-form articles) significantly helps over time.

Score voiding option: At the end of the exam, before seeing your score, you can choose to void your result. You won't receive a score, won't be charged, but the attempt still counts toward your lifetime limit. Use this only if you're certain you performed far below your baseline.


3. Scoring explained

Score rangeMidpointScore deliveryValidity
472–528 total500 (50th percentile)30–35 days after test2–3 years (varies by school)

Each section is scored 118–132; the four section scores are added for your total. A score of 500 represents the 50th percentile. Most competitive medical schools expect totals of 510–518+, with top programs averaging 520+.

What scores do medical schools expect?

Score rangePercentileCompetitive for
517–52895th–100thTop 10 MD programs (Harvard, Johns Hopkins, UCSF)
512–51685th–94thTop 25 MD programs

504–50760th–71stMost MD programs
500–50350th–58thDO programs; some MD programs
Below 500Below 50thConsider retaking

Score validity varies by school, most require scores within 2–3 years of your application date. Check each school's policy, especially if you're planning to take the MCAT well before you're ready to apply.


4. Prerequisites, when to take it

Unlike the GRE or LSAT, the MCAT has real academic prerequisites. You need substantial coursework before you're ready to sit for the exam.

Recommended coursework before taking the MCAT

SubjectRecommended coursework
Biology1 year intro biology + genetics + cell biology
General Chemistry1 year (with lab)
Organic Chemistry1 year (with lab)
Biochemistry1 semester minimum
Physics1 year calculus- or algebra-based
Psychology1 semester intro psychology
Sociology1 semester intro sociology
Statistics1 semester recommended

Most students take the MCAT in their junior or senior year of college, after completing the bulk of their prerequisites. Taking it too early, before finishing your science coursework, is one of the most common and costly mistakes pre-med students make.

Most students study 300+ hours. The AAMC recommends approximately 300 hours of total preparation. For most students, this translates to 3–6 months of consistent studying. Don't rush the timeline, a higher score is worth more than a faster application.


5. Test dates and scheduling

The MCAT is offered January through September only, it is not available in October, November, or December. In 2026, there are 31 test dates. See the full AAMC calendar for exact dates and score release dates.

MonthApproximate dates availableNotes
January4 datesGood for retakers and early planners
February1 date (new in 2026)Fills extremely fast, register immediately
March2–3 datesGood for early-cycle applicants
April4 datesLast "early" option for current cycle
May6 dates (most of any month)Most popular window, seats fill fast
June4–5 datesStrong option; scores back by July
July3–4 datesTight for current cycle but workable
August3–4 datesVery tight for current cycle
September2 dates (last: Sept 12)Scores back mid-October, too late for most current-cycle deadlines

You can take the MCAT up to 3 times in one calendar year, 4 times within two consecutive years, and a maximum of 7 times in your lifetime. All attempts, including voided scores, count toward these limits.

Register early. Popular test dates (especially May and June) fill within days of registration opening. The AAMC opens registration in October for January–September dates. Missing your preferred date can push your entire application timeline back by a year.


6. Planning around your application deadline

Medical schools use rolling admissions, applications submitted earlier receive interview invitations at significantly higher rates. Since scores take 30–35 days to arrive, you need to plan your test date carefully.

The rule of thumb: Take the MCAT by late April or May if you want to submit a complete application by June or July, the ideal window for rolling admissions. A June or July MCAT is the latest that comfortably allows current-cycle applications.

Complete your prerequisites first

Don't take the MCAT until you've finished the core science coursework. Testing too early is the most common and costly mistake.

Study 3–6 months

Plan 300+ hours of preparation. Build in content review, practice questions, and at least 3–5 full-length practice exams under timed conditions before your test date.

Account for score delivery

Scores arrive 30–35 days after your test. AMCAS (the medical school application system) opens in late May, your application can't be verified as complete without your MCAT score.

Leave room for a retake

You must wait until your score is released before retaking. A May test gives you retake options in July or August if needed, still workable for the current cycle.

Apply early in the cycle

AMCAS opens in late May/early June. Applications verified and submitted by June–July are at a significant advantage over October or November submissions for the same cycle.

Test dateScores arrive byApplication timing
March – AprilApril – MayIdeal, early cycle submission
MayJune – JulyStrong, still early in cycle
JuneJuly – AugustAcceptable, mid-cycle
JulyAugust – SeptemberTight, late cycle
August – SeptemberSeptember – OctoberToo late for current cycle, apply next year
