What are MCAT Score Percentiles? 

MCAT score percentiles compare us against everyone else taking the test. Gone are the days where everyone gets a trophy. With the MCAT, there are winners, losers, and then everyone else who falls in the middle of the bell curve. One could say that the percentile comparing you against the other test takers is actually more important than your score itself.

How MCAT Percentiles Work

The percentile measures how well your score compares to others who took the test. The percentile does NOT measure the percentage of questions you answered correctly. Let’s take this percentile example:

98th percentile: 98% of all test takers received the same score or lower. Simply put, a 98th percentile means that you are in the top 2% of all test takers.

Although there are big differences in content that is being tested between the old and new MCAT, you should understand that the importance of a high score and landing in the top percentiles remains equally important.
