NBME Score Calculator: How to convert percent correct on NBMEs to a 3-digit USMLE Step 1 score
Updated: Feb 9, 2020
If you took a practice NBME but only know the percent you got correct, how do you figure out an approximate 3-digit score?
I made an excel sheet to help students calculate their 3-digit score from their percent correct on NBMEs. Download it here for free! This is especially helpful for calculating a 3-digit score from the percent you got correct on the free online NBME sample questions.
Note: There is no perfect way to estimate scores. Each exam has a slightly different curve.
To see scatterplots of how NBME score correlates with actual USMLE Step 1 score, check out my article here https://www.medschoolgurus.com/blog/how-well-do-practice-tests-correlate-with-actual-usmle-step-1-scores.
If you're not happy with your score, you should really learn how to get into the mind of the test maker (the NBME) by reading my blog about the NBME's blueprint behind all of their questions.
