CMS forms average vs real Step 2 CK scores
Based on 602 real score reports. CMS forms average correlates with the final score (r = 0.59), but with wide spread: it is a useful signal, not a verdict. Students who went on to score 250+ averaged about 82%; those who scored 260+ averaged about 83%.
The lookup shows the average real score of students at that level, not a personalized prediction.

Common questions
What CMS forms average do you need for a 250 on Step 2?
Students who scored 250 or higher averaged about 82%, and those at 260 or higher averaged about 83%. There is wide spread around those averages, so treat them as context rather than cutoffs.
Is CMS forms average a good predictor of the real score?
It correlates with the real score (r = 0.59), but practice exams predict better. It works best combined with NBME or UWSA scores, which is what the full predictor does.
Get a real prediction, not a rule of thumb
The full predictor combines all of your practice tests with their timing, shows calibrated probability ranges, and was the most accurate of every predictor we benchmarked against real scores. See the head-to-head comparison.
