NBME 31 Conversion Is an Educational Estimate
USMLE Step 1 is reported as Pass/Fail for exams administered on or after January 26, 2022. This independent NBME 31 score conversion tool is for study planning only and is not affiliated with NBME, USMLE, FSMB, ECFMG, or UWorld.
How to use it
How the NBME 31 Score Conversion Calculator Works
Searchers for NBME 31 score conversion usually want a preset calculator, a percent-correct interpretation, and a cautious way to read readiness before Step 1.
Enter wrong answers or percent correct
Use wrong answers when your review notes show missed items. Use percent mode when your report or spreadsheet only gives a percent correct.
Read readiness, not an official score
Step 1 is Pass/Fail, so the useful output is whether the result is below, near, or above a practical passing-readiness range.
Compare with recent forms
NBME 31 is often taken late in preparation. Compare it with NBME 29, NBME 30, Free 120, and your recent timed blocks rather than one isolated number.
Turn misses into a plan
After calculating, tag missed questions by system, discipline, timing, and reasoning error so the estimate leads to targeted review.
Use the broad Step 1 page for multi-form trends
If you are comparing NBME 25-31 together, the general Step 1 converter is a better hub. This page is for Form 31-specific searches and examples.
Examples and edge cases
NBME 31 Score Conversion Examples
Use these examples to understand what the input means before making any scheduling decision.
Example: 60 wrong answers
Entering 60 wrong answers on NBME 31 produces an estimated historical Step 1 score around the high passing range. Treat it as a readiness signal, not a guaranteed result.
Example: 70% correct
For NBME 31, 70% correct is treated as about 60 missed questions out of 200 before conversion.
Borderline result
If the estimate sits close to the historical passing area, do not rely on one form. Review weak systems and confirm with another recent NBME or Free 120.
Strong result
A strong NBME 31 is more useful when it was timed, uninterrupted, and taken near your actual exam window. Untimed review can overstate readiness.

NBME 31 FAQ
NBME 31 Score Conversion FAQ
Is this NBME 31 conversion official?
No. It is an independent educational estimate and is not affiliated with NBME or USMLE.
Does Step 1 still report a three-digit score?
No. Step 1 is reported as Pass/Fail for exams administered on or after January 26, 2022, so this page uses historical score language only for readiness context.
Can I enter percent correct for NBME 31?
Yes. Percent mode converts the percentage to an estimated missed-question count out of 200 before calculating.
How many questions does this calculator use for NBME 31?
The calculator treats NBME 31 as a 200-question self-assessment.
Should I trust NBME 31 more than older forms?
Recent, timed forms are often more useful than old baselines, but consistency across multiple assessments matters more than one form.
What if my NBME 31 result is borderline?
Review weak areas, avoid deciding from one score, and confirm readiness with another recent NBME, Free 120, or school guidance.
Why is this separate from the Step 1 converter?
The Step 1 converter covers NBME 25-31 broadly. This page keeps Form 31 selected and answers Form 31-specific searches.
Does this replace my official NBME report?
No. Use the official NBME report and your school guidance as the primary sources.
