No one has ever scored 100% on the MCAT. That’s because the MCAT is not scored as a percentage.
The MCAT uses a scaled score ranging from 472 to 528. It has four sections: Biological Sciences, Chemical Sciences, Psychological Sciences, and Critical Analysis. Each section is scored from 118 to 132. A perfect MCAT score is 528.
Why “100% on MCAT” Is a Misconception
Test takers sometimes say “100%” to mean a perfect score. But the MCAT doesn’t measure percent correct in a simple way. The exam is scaled and equated to account for question difficulty. Your raw score (number correct) is converted to a scaled score. So, even top scorers don’t answer every question correctly.
The Association of American Medical Colleges (AAMC) confirms no 100% on MCAT exists. Instead, students aim for the 99th percentile, often around 520–528. Only about 0.1% of test takers reach a perfect 528.
Scoring high requires strong content knowledge and critical thinking. But perfection isn’t about getting every question right. It’s about performing better than nearly all other test takers.
If you’re preparing for the MCAT, focus on consistent practice. Use official AAMC materials to understand how scoring works. Aim for your best scaled score—not a mythical 100% on MCAT.
There’s no such thing as 100% on the MCAT. The scoring system simply doesn’t work that way.
Understanding this helps set realistic and effective study goals.
