USMLE Step 3 Question Banks: UWorld vs. Kaplan vs. BoardVitals

usmle step 3 doctor typing

Are you preparing for your USMLE Step 3 Exam? The USMLE Step 3 exam had a 98% pass rate in 2019 among all test takers and thus, has become notoriously one of the easier USMLE exams. Nonetheless, studying is important to secure your passing grade. The exam takes two separate (non-consecutive) days, with much longer question stems than those found on Steps 1 and 2. Timing and pacing are critical in performing well on this exam. A mix of practice questions for topic-based review is the best way to ace your exam and maintain confidence.

It can be hard to weed through the many options at your disposal for studying, and we get lots of questions about how BoardVitals’ USMLE Step 3 question bank differs from Kaplan and UWorld, so we’re laying it all out for you. We have talked to a few doctors and here’s a quick guide on what they noted as consequential differences.

“[Besides question banks, I recommend] flashcards — these are crucial for mastering memorization content: pharmacology, embryology, biochemistry, immunology, and microbiology,” Christopher Carrubba, MD* said.

BoardVitals provides question banks specifically for students and practitioners preparing for medical licensing and certification exams. These questions are written and reviewed by those who have recently taken the exams. With this information, users can sort their questions based on high ratings, thus prioritizing those questions other doctors have found the most useful.

BoardVitals’ USMLE Step 3 Question bank provides users with more than 1,550 questions with costs ranging from $109 for 1 month, $169 for 3 months and $249 for 6 months.

Feedback & Customer Service

BoardVitals has a feedback link on each question, which enables users to ask questions and get additional feedback from other doctors. BoardVitals has physicians on staff that respond to inquiries and update the content daily. This is a great feature for students who may need clarification other than what was provided in the detailed explanations. Customer service is available 24/7 via email [[email protected]] and via phone [877.221.1529] during normal business hours.


The question bank covers all topics for the step 3 exam. The major drawback to this resource is that CCS (Computer-based Case Simulations) cases aren’t available for practice. CCS cases are a major part of the step 3 exam and make up half of the second test day (there are 13 CCS cases per exam). You don’t want to go to the test without practicing some actual cases first. Having the knowledge is one thing, and practicing on the software is another thing.

“BoardVitals provides a concise, high-yield study tool for busy interns and it also has features that allow questions to be incorporated into didactic sessions throughout the academic year,” Bisi Akindele, MD, said.

Additional Features

  • BoardVitals features an eBook on how to prepare for and pass the Step 2 and 3 exams. This was put together by high-scoring professionals – it’s a great guide.

“I used this qbank and the CCS cases for my step 3. The format of the CCS cases was very similar to the exam itself. I discovered so many different ways to order tests, medications, counseling options that I otherwise wouldn’t have thought to use if I had taken the test without practicing first,” Akindele said.
