This page opens with Step 1, NBME, and Form 33 already selected. Keeping the exact form matters because Step 1 CBSSA curves differ by form.

NBME 33 Conversion Is an Educational Estimate
This independent NBME 33 tool converts your input to an estimated raw percent correct for study planning. It cannot reproduce NBME equating, probability of passing, or an official score report and is not affiliated with NBME, USMLE, FSMB, ECFMG, or UWorld.
How to use it
How the NBME 33 Score Conversion Calculator Works
Searchers for NBME 33 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 33 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 25-33 together, the general Step 1 converter is a better hub. This page is for Form 33-specific searches and examples.
Examples and edge cases
NBME 33 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 a 200-question input gives an estimated raw percent correct of 70%. This is arithmetic, not NBME equating or an official probability of passing.
Example: 72% correct
Percent mode keeps 72% as the estimated raw percent correct and shows a narrow rounding range. Compare it with the equated percent correct on your official NBME report.
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 33 is more useful when it was timed, uninterrupted, and taken near your actual exam window. Untimed review can overstate readiness.

NBME 33 FAQ
NBME 33 Score Conversion FAQ
Is this NBME 33 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. This page reports an estimated raw percent correct and does not claim an official three-digit conversion.
Can I enter percent correct for NBME 33?
Yes. Percent mode preserves the entered percentage as an estimated raw percent correct; it does not reproduce NBME equating.
How many questions does this calculator use for NBME 33?
The calculator treats NBME 33 as a 200-question self-assessment.
Should I trust NBME 33 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 33 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 broader Step 1 converter covers established Form 25-31 estimates. This page isolates the newer Form 33 search intent and uses a safer raw-percent output.
Does this replace my official NBME report?
No. Use the official NBME report and your school guidance as the primary sources.
