Why Students Prefer Our USMLE Practice Exams

Alongside the NBME®’s practice exams, our USMLE self-assessments are considered by students to be the most helpful at gauging exam readiness. Our test forms are highly representative of the real exam, offer accurate score predictions, and deliver detailed score reports to help with remediation.

Simulated USMLE Interface

Our self-assessments look and feel like the real exam to build your familiarity with the testing software and boost your confidence.

Explanations for Each Question

Once you complete a self-assessment, we provide QBank-style rationales for each question to help you learn from your mistakes.

Comprehensive Score Reports

Your UWorld score report will contain an approximate 3-digit USMLE score, your relative ranking, and your results by subject and system.

Practice the USMLE’s “Block” Format

Each UWorld self-assessment features four 60-minute blocks with 40 unique MCQs per block. This is similar to Step 1’s 7 blocks, Step 2 CK’s 8 blocks, and Step 3’s 6 blocks on testing day one. We currently offer:

  • 3 Step 1 Self-Assessments
  • 3 Step 2 CK Self-Assessments

Frequently Asked Questions

Our self-assessments (sometimes referred to as UWSAs) reflect what students can expect on their Step exams. We mirror the testing interface, difficulty level, question types, and format to offer a realistic measurement of your readiness.

For Step 1 and Step 2 CK, we suggest taking Form 1 early in your prep as a baseline measurement of your understanding, Form 2 in the middle or toward the end of your initial studies to identify weaknesses, and Form 3 during dedicated study as a final performance check.

For Step 3, we suggest taking Form 1 during the beginning or middle of your first year of residency, and Form 2 in the final weeks before your exam date to get reacclimated to the USMLE testing environment.

Each of our practice tests consists of four 60-minute blocks with 40 unique multiple-choice questions per block. This means that each self-assessment contains 160 USMLE-style questions with thorough answer explanations that can’t be found in our QBank.

Our self-assessments all feature four 60-minute blocks; however, you have the option to set your time limit to 1x, 1.5x, or 2x to simulate an extended-time accommodation. You can also pause the exam and return to it later as needed.

Many students and educators consider UWorld USMLE practice exams to be as accurate as the NBME’s practice tests at gauging true exam readiness.

Yes, we currently offer 3 self-assessments for Step 1 and Step 2 CK, and 2 self-assessments for Step 3. They can be purchased individually or in bundles by Step product.
