How to interpret USMLE scores

You will get the following info in your USMLE report :
your 3-digit score
your 2-digit score
Mean and Standard Deviation for recent US/Can registrants (not IMGs) - first time test takers.


This is a common misperception to call 2-digit score percent or percentile - 2 totally different things, by the way; it's neither percent, nor percentile!

From biostatistics you should know that percentile is the percent of people from total 100% who received scores lower than yours.

By using your 3-digit score, Mean and Standard Deviation and special statistical table, you can calculate your percentile, and by using your 2-digit score, you can calculate appr. percent of correctly answered questions.
