Every fall, the NBME releases 150 sample questions for candidates to see what USMLE Step 1 questions look like. They publish the items on CD-ROM; they also can be downloaded from the USMLE web site. It is important for you to review these items, as they are similar in both format and content to those on the real exam.

What the NBME doesn't provide are the explanations. That's where Kaplan Medical comes in! We have written comprehensive explanations to all 150 items, including discussions of why the right answers are right and why all the distracters are wrong. Please note that the questions themselves are copyrighted by the NBME and can not be reproduced. If you don't already have the USMLE's CD-ROM, visit www.usmle.org.
