If you are looking at a 488 on your score report, take a breath. This page is not going to lecture you. It is going to give you the facts: where a 488 sits, what it usually reflects, and what students in this range tend to do next.
On the official AAMC percentile table, a 488 is in the 16th percentile. The MCAT total scale runs from 472 to 528, and the national mean is 500.6. Percentile ranks come from the official AAMC percentile table in effect May 1, 2026 to April 30, 2027, based on all MCAT results from the 2023, 2024, and 2025 testing years combined (N = 305,494).
What a 488 usually reflects
A score in this range usually means the foundations were not fully in place on test day. That can be content gaps, but just as often it is the compounding of timing pressure, unfamiliarity with how the AAMC writes questions, and test-day nerves. It rarely means you are not capable of this exam.
The useful move is diagnostic, not emotional: look at your section breakdown (C/P, CARS, B/B, P/S) and ask where the points actually went. A 488 built on one very low section is a different situation than a 488 spread evenly across all four.
If you are considering taking it again
Many students who score in this range do sit the exam again, and a retake from here is best treated as a rebuild rather than a patch. That means a structured plan that puts content foundations first, layers in passage practice gradually, and saves the official AAMC full lengths for when they can teach you the most.
We will not tell you what score a retake will produce. Nobody can promise that honestly. What we can say is that students who improve from this range usually change how they study, not just how much.
How Retakers approach it differently
A Retaker is not a first-timer with a bad memory of test day. You have seen the real exam, you have a score report, and you know what the room feels like. That is real information a first-timer does not have.
The Retaker approach starts with your error patterns: which sections leaked points, which question types went wrong, and what the wrong answers you picked have in common. Build the plan around that, and every study hour starts pulling in the same direction.
Common questions about a 488
Is a 488 MCAT score good?
A 488 sits in the 16th percentile on the official AAMC percentile table, meaning 16% of MCAT scores were equal to or lower. Whether it is "good" depends on your goals, your target programs, and the rest of your application.
What percentile is a 488 MCAT score?
On the AAMC percentile table in effect May 1, 2026 to April 30, 2027, a total score of 488 is in the 16th percentile. That means 16% of scores were equal to or lower than 488.
Should I retake the MCAT with a 488?
Most students scoring in this range who still want to pursue medicine do plan a retake, and the strongest retakes from here start with a structured rebuild of content foundations rather than jumping straight into practice exams. Give yourself enough runway, and build the plan around your actual error patterns from the first attempt.
