NBME 10 Conversion Is an Estimate
This independent NBME 10 score conversion tool uses a practical conversion model for study planning. It is not affiliated with NBME, USMLE, FSMB, ECFMG, or UWorld, and it should not replace official reports or school guidance.
How to use it
How the NBME 10 Score Conversion Calculator Works
Searchers looking for NBME 10 score conversion usually want a fast answer first, plus enough context to decide whether the result is reassuring, borderline, or below target.
Enter wrong answers or percent correct
If your review notes show missed questions, enter that count. If you only know your percent correct, switch the input mode and the tool will convert it using the 200-question NBME 10 total.
Read the range, not only one score
The displayed score is paired with a range because online conversion models cannot reproduce every official scoring detail. Treat a narrow pass margin as a prompt for another timed assessment.
Compare with the 218 passing line
For exams administered on or after July 1, 2025, the current Step 2 CK minimum passing score is 218. Results near that line deserve extra caution.
Use the result with your trend
NBME 10 is more useful when compared with NBME 9, NBME 11-16, UWSA, Free 120, and recent timed question blocks. A consistent trend is stronger than one isolated result.
Plan the next study block
After calculating, tag missed questions by medicine, surgery, pediatrics, OB/GYN, psychiatry, ethics, and biostatistics so the estimate turns into an actionable review plan.
Examples and edge cases
NBME 10 Score Conversion Examples
Use these examples to understand the input and output before relying on a score estimate.
Example: 42 wrong answers
Entering 42 wrong answers on NBME 10 produces an estimated Step 2 CK score near the mid-240s with a range around it. That is usually above the passing line, but the final decision should still consider timing and trend.
Example: 72% correct
For NBME 10, 72% correct is treated as about 56 missed questions out of 200 before conversion. Percent mode is helpful when your notes do not include an exact missed-question count.
Borderline results
If the estimate or range overlaps 218, avoid using one conversion as a scheduling decision. Review weak systems and confirm with another recent NBME or UWSA.
High scores still need context
A strong NBME 10 result is more reliable when the exam was timed, uninterrupted, and taken close to your actual Step 2 CK date. Untimed review sessions can inflate confidence.

Yes. Switch to percent correct and enter a value from 0 to 100. The tool converts that percentage into an estimated missed-question count before calculating.

What passing score should I compare my NBME 10 result with?
For Step 2 CK exams administered on or after July 1, 2025, the current minimum passing score is 218.
Should I use NBME 10 or a newer NBME form?
NBME 10 can be useful for trend review, but a newer timed NBME taken closer to test day may be more relevant for final scheduling.
Why does the calculator show a score range?
A range reflects the uncertainty of online conversion models, form difficulty, and test-day variation. Use it to guide decisions instead of relying on one point estimate.
What should I do if my NBME 10 estimate is borderline?
Review missed questions by system and discipline, build a score buffer, and confirm readiness with another recent NBME or UWSA before making a final exam-date decision.
