Questions people ask
Is this diagnostic the same length as the USMLE Step 2 CK exam?
No. The real exam runs up to 318 questions in eight 60-minute blocks over one day. This set has 37 questions in 56 minutes, which works out to about 2 minutes per question, the same pace as a real block.
How are the 37 questions chosen?
They come from the free sample of the PassExams USMLE Step 2 CK bank and follow the USMLE weights for each system. Areas that carry more questions on the real exam get more questions here.
Does a score here predict whether I will pass?
No single set of 37 questions can. Use it to find the areas that need work, then take it again after a few weeks of practice and compare the two reports.
Do I need an account?
No. Your answers stay in this browser and nothing is uploaded. You can save the report as an image when you finish.
