NBME 11 to Step 2 CK conversion
Based on 1,950 real score reports that included an NBME 11 result. The actual Step 2 score was about 12 points higher than the NBME 11 score, on average. Used alone, an NBME 11 score predicts the real result with a typical error of about ±6.3 points. Combining multiple tests usually reduces the error.
Each dot is one real report: their NBME 11 result against the Step 2 CK score they went on to get. Hover or tap a dot to see that person's full test list. r = 0.69, n = 1,902.
The calculator assumes the test was taken about 24 days before the exam, the typical timing in the underlying reports. Taking it closer to test day shifts the prediction; the main predictor uses your exact timing and every other test you have taken.
Common questions
Does NBME 11 underpredict your Step 2 score?
In the collected score reports, NBME 11 underpredicted the actual score by about 12 points on average. The conversion accounts for that average difference.
How accurate is NBME 11 alone at predicting Step 2?
A single NBME 11 score predicts the real result with a typical error of about ±6.3 points. The main predictor combines several tests, which usually reduces the error.
How do I convert my NBME 11 percent correct to a score?
Enter your raw percent correct above. NBME 11 has 200 questions, so each one is worth about half a percent; the converter maps your percent to the 3-digit NBME 11 score (about 2.2 points per percent, calibrated on real reports and cross-checked against published conversions) and then to a predicted Step 2 CK score.
Convert NBME 11 % correct to a 3-digit score
Took NBME 11 offline and only have a raw percent correct? Estimate your 3-digit form score below — it also fills into the calculator at the top of the page, so you still get a Step 2 prediction.
