The MCAT is scored on a scale of 472 to 528, with 500 as the midpoint. The exam has four sections, each scored from 118 to 132, and your total score is the sum of all four. There is no penalty for wrong answers, so every question you leave blank counts the same as a wrong guess.
The Four Scored Sections
Each section of the MCAT receives its own scaled score from 118 to 132, with 125 as the midpoint. The four sections are:
- Chemical and Physical Foundations of Biological Systems: physics, general chemistry, organic chemistry, and biochemistry as they apply to living systems
- Critical Analysis and Reasoning Skills: reading comprehension and analytical reasoning based on passages from the social sciences and humanities
- Biological and Biochemical Foundations of Living Systems: biology, biochemistry, and organic chemistry
- Psychological, Social, and Biological Foundations of Behavior: psychology, sociology, and biology as they relate to human behavior and health
Your total score is simply the four section scores added together. A perfectly average performance across all sections would yield a 500 (125 × 4), while a perfect score is 528.
How Raw Scores Become Scaled Scores
Your raw score on each section is the number of questions you answered correctly. Wrong answers and unanswered questions are treated identically, meaning there is no guessing penalty. If you’re unsure, picking an answer gives you a chance at a point you’d otherwise lose.
That raw count is then converted to the 118–132 scaled score through a process called equating. Because different test dates use different sets of questions, some versions end up slightly harder or easier than others. Equating adjusts for this so that a 125 on one test date means the same thing as a 125 on another. The exact conversion from raw to scaled changes with every test form, and the AAMC does not publish the conversion tables.
What the Percentiles Look Like
Percentile ranks tell you what percentage of test-takers scored at or below a given number. The AAMC updates these annually using three years of combined data. The current ranks, in effect through April 2026, are based on everyone who tested in 2022, 2023, and 2024.
A total score of 500 lands at the 49th percentile, almost exactly the middle of the pack. Scoring a 501 puts you at the 52nd percentile. To reach the 90th percentile, you need roughly a 515. And the 99th percentile begins at 522, meaning only about 1 in 100 test-takers scores that high or above.
For context, the mean total MCAT score among students who actually enrolled in U.S. MD-granting medical schools for the 2023–2024 cycle was 511.7, with a standard deviation of 6.9. That means most successful applicants scored somewhere between about 505 and 519, though scores outside that range certainly get in depending on the rest of the application.
Confidence Bands on Your Score Report
No standardized test measures your ability with perfect precision, and the MCAT acknowledges this through confidence bands. Your total score is reported with a band of plus or minus 2 points, and each section score carries a band of plus or minus 1 point. If your total score is 510, your true ability likely falls somewhere between 508 and 512.
This matters most when comparing two applicants with similar scores. A 510 and a 512 have overlapping confidence bands, so those scores are not meaningfully different. Admissions committees are encouraged to treat them as essentially equivalent.
When You Get Your Scores
Scores are released approximately 30 to 32 days after your test date. The AAMC publishes exact release dates for every testing window, and scores go live by 5:00 p.m. Eastern on the scheduled day. For the 2026 testing year, someone testing on January 9 would receive scores on February 10, and someone testing on September 12 would see results on October 13.
Planning your test date around score release is important if you’re applying in a rolling admissions cycle. Many applicants aim to test early enough that their scores arrive before or shortly after medical school applications open, since later scores can delay the review of your file.
What Your Score Report Includes
Your official report shows each of the four section scores, your total score, the confidence bands for each, and your percentile ranks for both individual sections and the total. If you’ve taken the MCAT more than once, all scores appear on your report, though the AAMC notes that medical schools vary in how they use multiple scores. Some look at your highest total, some average across attempts, and some focus on the most recent sitting.
The score report does not break down performance by individual question or topic area. You won’t know which specific questions you got right or wrong, only how your overall section performance translated to the scaled score.
