Keep the form set to NBME 15
This page opens with Step 2 CK, NBME, and Form 15 already selected. Keeping the correct form matters because each self-assessment has its own curve and question count.

Important limitation
NBME 15 Conversion Is an Estimate
This independent NBME 15 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 15 Step 2 Score Conversion Works
Students searching for NBME 15 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
Use wrong-answer mode if your review screen shows missed items. Use percent-correct mode when you only recorded a percentage and need a fast Step 2 CK estimate.
Read the range, not only one score
The output includes a score range because independent online conversion models cannot reproduce every official scoring detail. A narrow pass margin should trigger another timed check.
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 15 as part of a trend
NBME 15 is often used as a later Step 2 CK readiness check, so compare it with NBME 13, NBME 14, NBME 16, UWSA, Free 120, and timed question-block performance.
Turn the result into a study plan
After calculating, sort missed questions by discipline, system, timing issue, and reasoning error. The score estimate is most useful when it leads to targeted review.
Keep NBME 15 conversion separate from broad calculator searches
This page is for a result from Form 15. It explains the NBME 15 Step 2 score conversion inputs, keeps Form 15 selected, and links to the broader Step 2 CK calculator only when comparing several forms is the real task.
Examples and edge cases
NBME 15 Score Conversion Examples and Edge Cases
Use these NBME 15 score conversion examples to understand wrong-answer input, percent-correct input, and a result near the 218 Step 2 CK passing line.
Example: 38 wrong answers
Entering 38 wrong answers on NBME 15 produces an estimated Step 2 CK score with a range around it. Treat the result as a planning signal, not an official score.
Example: 81% correct
For NBME 15, 81% correct is treated as about 38 missed questions out of 200 before conversion. Percent mode is useful when your notes do not include the 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.
Very high or very low inputs
Extreme results can be less stable because unofficial conversion models are estimates. Use them to frame review priorities, then confirm with another timed exam.

NBME 15 Inputs and Step 2 CK Conversion Choices
Use this table to choose the right input mode and decide when a broader calculator or another assessment is a better comparison.
| Use case | Input | Best next step |
|---|---|---|
| NBME 15 wrong-answer conversion | 0–200 missed questions | Use this page when your NBME 15 review shows the number of missed items. |
| NBME 15 percent correct | 0–100 percent correct | Use percent mode when you only have a percentage for NBME 15. |
| Other Step 2 CK NBME forms | NBME 10–16 | Use the broader calculator when the result is not NBME 15. |
| UWSA or Free 120 comparison | UWSA 1–3 or Free 120 | Use another assessment family when you need a second readiness signal. |
