NBME 9 Conversion Is an Estimate
This independent NBME 9 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 NBME 9 Step 2 Score Conversion Works
Students searching for NBME 9 score conversion usually want the form-specific calculator first, then enough context to read the score range without treating one self-assessment as an official prediction.
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 9 total.
Read the range, not only one score
The displayed score is paired with a range because independent 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 NBME 9 as part of a trend
NBME 9 is an older Step 2 CK form, so compare it with NBME 10–16, UWSA, Free 120, and recent timed question blocks instead of using one result as a final prediction.
Turn the result into review priorities
After calculating, tag missed questions by medicine, surgery, pediatrics, OB/GYN, psychiatry, ethics, and biostatistics so the estimate becomes an actionable study plan.
Keep NBME 9 conversion separate from broad calculator searches
This page is for a result from Form 9. It explains the NBME 9 Step 2 score conversion inputs, keeps Form 9 selected, and links to the broader Step 2 CK calculator only when comparing several forms is the real task.
Examples and edge cases
NBME 9 Score Conversion Examples and Edge Cases
Use these NBME 9 score conversion examples to understand wrong-answer input, percent-correct input, and a result near the 218 Step 2 CK passing line.
Example: 45 wrong answers
Entering 45 wrong answers on NBME 9 produces an estimated Step 2 CK score with a range around it. Treat the result as a planning signal, not an official score.
Example: 78% correct
For NBME 9, 78% correct is treated as about 44 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, do not make a scheduling decision from one conversion. Review missed concepts and confirm readiness with another recent NBME or UWSA.
Older-form context
NBME 9 can support trend review, but newer timed forms taken closer to test day may be more useful for final scheduling decisions.
