blueey,
i was just getting online to look for the answer to the same question. . . The NMS Step 2 CD-ROM says 55-60% correct correlates with passing, >75% correct correlates with a well-above average score. But obviously qbank is a different set of questions entirely.
Here's what Kaplan said when i asked them a similar question:
Hello,
Thank you for using Kaplan's cutting edge Qbank!
The Qbank has the most test-like questions available; it is the perfect
tool for honing your skills on the various USMLE question types.
However, the Qbank is not designed to simulate a full-length testing
experience. We haven't conducted large-scale longitudinal studies of
the predictive validity of Qbank, as the Qbank allows students to
customize exams, and therefore doesn't replicate the actual test
experience.
Thus, the performance percentages you receive do not correlate to
official USMLE test scores.
Best regards,
