Common questions
What is the passing score for Step 2 CK?
The minimum passing score is 214. The vast majority of US MD first-takers pass, and in the collected reports practice-test averages above the low 220s were associated with passing in nearly every case.
What practice scores suggest you are ready to pass?
In real score reports, students averaging 220 or higher on scaled practice tests passed in over 99% of cases. Below the low 210s the risk becomes meaningful, and many students choose to postpone.
