The MCAT is scored on a scale from 472 to 528. That total comes from four sections, each scored from 118 to 132, with 500 representing the midpoint of the scale. The scoring system can feel unusual if you’re used to percentage-based tests, so here’s how it actually works.
How the Four Sections Add Up
The MCAT has four multiple-choice sections, each worth between 118 and 132 points:
- Biological and Biochemical Foundations of Living Systems
- Chemical and Physical Foundations of Biological Systems
- Psychological, Social, and Biological Foundations of Behavior
- Critical Analysis and Reasoning Skills
Your total score is simply the sum of those four section scores. A perfect score on every section (132 x 4) gives you a 528. The lowest possible score on every section (118 x 4) gives you a 472. The midpoint for each section is 125, making 500 the midpoint of the total scale.
How Raw Scores Become Scaled Scores
Your raw score on each section is based on the number of questions you answer correctly. There is no penalty for guessing, so you should answer every question even if you’re unsure. That raw score is then converted to the 118-to-132 scaled score through a process called equating, which adjusts for small differences in difficulty between test forms. This means a 125 on a slightly harder version of the test represents the same level of performance as a 125 on a slightly easier version, regardless of when you took the exam or who else tested that day.
What Counts as a Good Score
Because the scale is designed so that 500 falls at the center, scoring a 500 means you performed right around the median of all test takers. Each section’s midpoint of 125 works the same way. Scores are distributed in a bell curve, so most people cluster near the middle and relatively few reach the extremes.
A score of 510 or above generally puts you well above the 50th percentile and makes you competitive at many medical schools. Scores above 520 place you in roughly the top few percent of all test takers. But competitiveness depends heavily on which schools you’re applying to. Schools publish their median and percentile data for accepted students, so you can compare your score directly against the entering class at programs you’re considering.
How Long MCAT Scores Last
Medical schools generally accept MCAT scores dating back two or three years, though the exact policy varies by school. If you took the exam several years ago and are planning to apply, check the admissions requirements at each school on your list before assuming your score is still valid. Some programs are stricter than others about the cutoff.
Why the Scale Looks Odd
The 472-to-528 range exists by design. The AAMC chose a scale that wouldn’t be confused with older versions of the MCAT (which used a different scoring system) or with other standardized tests. The narrow range also reflects the test’s purpose: it’s meant to differentiate among a relatively similar pool of high-achieving pre-med students, not to spread scores across a massive range. A few points on this scale can represent a meaningful shift in your percentile ranking, which is why medical schools pay close attention to both total and section-level scores.
