MCAT scoring explained: how the 472–528 scale maps to medical school admissions

How a raw score becomes a 472–528 number

On test day you answer 230 multiple-choice questions across four sections. Your raw score is the number of correct answers in each section. AAMC then converts these raw counts to a scaled score between 118 and 132 for each section, using a statistical equating process that accounts for slight differences in difficulty between test forms.

The four section scores add to a total between 472 and 528. The midpoint of the scale is 500, which corresponds roughly to the median test-taker. The 90th percentile sits around 514, and a 520+ score puts you in the top 5% of all examinees.

There are no penalties for wrong answers, so leaving questions blank is always worse than guessing. The scaling process means that two students who answered different specific questions can end up with the same scaled score if their relative performance was equivalent.

Your scaled score reflects how you performed relative to a stable reference group, not your raw percentage.

What each section measures and how it scores

The four MCAT sections each score 118 to 132, with 125 as the median. The sections are: Chemical and Physical Foundations of Biological Systems (Chem/Phys), Critical Analysis and Reasoning Skills (CARS), Biological and Biochemical Foundations of Living Systems (Bio/Biochem), and Psychological, Social, and Biological Foundations of Behavior (Psych/Soc).

CARS is the only section without a content basis. It tests reading comprehension and reasoning using passages from humanities and social sciences. Many students see their lowest section score here even when their content sections are strong, because CARS does not respond to memorization.

Score balance matters as much as total score. A 510 with 130/120/130/130 looks very different to admissions than a 510 with 128/127/127/128. The balanced score signals consistent competence; the imbalanced score raises questions about the weak section.

• Chem/Phys: gen chem, physics, organic chem, with biochem applications.
• CARS: reading and reasoning, no content basis.
• Bio/Biochem: biology, biochemistry, with some organic chem.
• Psych/Soc: psychology, sociology, with some biology.

What admissions committees actually see

Admissions committees receive your section scores, total score, percentile ranks, and a confidence band around each score. The confidence band acknowledges that a single test administration cannot perfectly capture ability; AAMC reports a typical band of plus-or-minus 1 to 2 points per section.

Most U.S. allopathic schools publish median accepted MCAT scores. The 2025 cycle median for matriculants at U.S. MD programs was around 511 to 512 total, with significant school-to-school variation. Top-25 research-focused programs often have medians at 518+, while many state schools and primary-care-focused programs accept students in the 506 to 512 range.

DO programs typically have lower median MCATs, often in the 502 to 506 range, and weight clinical experience and mission fit more heavily. International medical schools vary widely; some accept much lower scores, but residency match outcomes are an important downstream consideration.

Pick target schools whose median is at or below your projected score, with two reach schools where you are at the 25th percentile.

When a retake helps and when it hurts

A retake helps when your score is significantly below your school list's 25th percentile and you have a concrete plan to fix the gap. It does not help if you score around the median and want to chase a number; the variance in admissions outcomes between, say, a 512 and a 515 is small relative to the rest of your application.

Most schools see all your MCAT scores. Some take the highest, some take the most recent, and a few average them. A second score that is 4+ points higher is a clear positive signal; a flat or lower second score is a meaningful negative signal.

If you are considering a retake, give yourself at least three months of dedicated repair work, focused specifically on the sections that pulled the total down. Do not retake without a clear hypothesis about why the first score was below your potential.

How to track score progress during prep

Your full-length scores are not just summative — they are your most accurate predictor of test-day performance. Practice tests from AAMC are the gold standard. Third-party full-lengths (Blueprint, Kaplan, Princeton Review, etc.) tend to score 2 to 6 points lower than your eventual MCAT score, so use them for skills practice but anchor your prediction on AAMC tests.

Track section-level trends, not just totals. A flat total can mask a falling CARS score and a rising Bio score, which would tell you exactly where to spend the next two weeks. Build a simple spreadsheet or use a prep platform that surfaces these section trends automatically.

• Use AAMC full-lengths for score prediction.
• Use third-party tests for skills practice, not score targets.
• Track section-level trend lines, not just total score.
• Expect 1–3 points of variance between consecutive practice tests.
