USMLE Step 2CK Question Banks: UWorld vs. Kaplan vs. BoardVitals


If your USMLE Step 2CK exam is coming up, you’ve come to the right place to figure out exactly how to review. To start, let’s make sure we know what we’re tackling. The exam is a one-day, nine-hour exam, and is typically found to be harder than the other Step exams. There are eight sets of questions and each set has a maximum of 40 questions. You have one hour to complete each set. For correct pacing, practice with question banks, giving yourself on average 80 seconds to answer each.

“The best way to obtain a high score on Step 2 is to master the test-taking strategy necessary for these types of questions (i.e. what is the next best step in management or what is the diagnosis). USMLE World is the best question bank — but BoardVitals, Kaplan, and Online MedEd each have question banks that are very high-yield and would be beneficial,” Christopher Carrubba, MD*, said.

We are always fielding questions about how our USMLE Step 2CK Question Bank differs from Kaplan and UWorld, so we talked to a few doctors to help you compare them and break down some of the major differences.
