USMLE® Step 1 Question Banks: UWorld vs Kaplan vs BoardVitals

USMLE Step 1 Questions

Are you getting ready to take your USMLE® Step 1 exam? We get asked all the time about how the BoardVitals Step 1 Question Bank compares to UWorld and Kaplan’s, so we talked to a few MDs to get the inside scoop.

The Step 1 exam is a one-day, 8-hour exam, divided into seven 60-minute blocks. The number of questions per block varies, but never exceeds 40, which would suggest that timing is not the biggest problem, but is something everyone should take into account. The total exam has at most 280 questions and allows test-takers to jump around to answer questions on their own accord.

There are so many different products, each with their own pros and cons, available to students, how do you know what is the best for you? We’ve got a detailed comparison of major USMLE Step 1 question banks to consider just for you. Check out what Kaplan, UWorld,and BoardVitals has to offer.

The Qbank also has “timed,” “tutor” and “timed tutor” modes.

“USMLE World is the most used and highest yield question bank. Students should try to complete it at least once (preferably twice) before their exam,” said Christopher Carrubba, MD, co-director of tutor development and medical education for Med School Tutors. “However, more questions are better! Utilizing BoardVitals and Kaplan question banks can only help your score.”

Additional Features

  • UWorld provides two 4-block assessments (can be purchased in combination with a question bank or alone).

Since the real exam is 7 blocks of questions, you can combine the 2 assessments for 1 practice session.
  • Mobile app available.

“In my opinion, the assessments may overestimate your preparedness and isn’t the best prediction for the actual test,” Akindele said
