More Clarity at Every Step
Alongside NBME® practice exams, our self-assessments are considered by many students to be the most helpful at gauging exam readiness. Each test form uses unique questions created by practicing physicians and exam experts to deliver a realistic testing experience.

You can also mark questions, strike out answers, and review enhanced exhibit displays just like you will on test day.

Get the Most Out of Your Practice Exams
Many students take several USMLE practice tests to gauge their readiness and prepare for their exams. Here’s how we suggest using UWorld self-assessments to maximize their value:
Form 1: Take early in your preparation for a baseline measurement of your knowledge.
Form 2: Take toward the middle or end of your initial studies to identify weaknesses.
Form 3: Take during dedicated study close to your exam date to get acclimated to the exam.
Form 1: Take at the beginning of your dedicated study period to establish a starting point.
Form 2: Take after completing half of the UWorld QBank.
Form 3: Take in the last 1-2 weeks of your study period.
Form 1: Take at the beginning or middle of your first year of residency to establish a baseline.
Form 2: Take in the last few weeks of your study time to get acclimated to the testing environment.

Frequently Asked Questions
How do UWorld's USMLE self-assessments work?
Our self-assessments (also called UWSAs) mirror the testing interface, difficulty level, question types, and format of each Step exam, giving you a realistic measurement of readiness before test day.
How many questions are in a USMLE self-assessment?
Each UWorld self-assessment includes 160 USMLE-style multiple-choice questions with thorough answer explanations that are not available in the QBank.
How long are UWorld USMLE self-assessments?
UWorld self-assessments are divided into 8 blocks, each containing 20 questions covered in 30 minutes. This mirrors the USMLE’s updated testing format and exam-day pacing. However, you can choose to set your pace at 1x, 1.5x, or 2x timing to simulate extended-time accommodations. You also have the flexibility to pause your assessment and return to it later as needed.
How accurate are UWorld USMLE self-assessments?
Many students and educators consider UWorld self-assessments as useful as NBME practice exams for gauging exam readiness. UWorld’s advantage is a more detailed score report plus full answer explanations for every question.
Can I purchase USMLE self-assessments individually?
Yes. UWorld offers 3 self-assessments for Step 1, 3 for Step 2 CK, and 2 for Step 3. They can be purchased with a QBank subscription, individually, or as a bundle.
What does my USMLE assessment score tell me?
Your UWorld score report includes an approximate 3-digit USMLE score* (based on historical UWorld data), an EPC score adjusted for form difficulty, and a breakdown of your performance by subject and system. This performance data is designed to help you determine your readiness and recalibrate your study plan to target weaknesses.
*The real Step 1 exam is pass/fail. Your estimated 3-digit score is intended to show your margin above passing.
Do UWorld’s Step 3 self-assessments include CCS cases?
No. Our Step 3 self-assessments only feature 8 blocks of multiple-choice questions. To practice CCS cases, we encourage you to subscribe to our Step 3 QBank.
Are UWorld's USMLE self-assessments adaptive?
No. UWorld’s self-assessments use a fixed block format that mirrors the actual USMLE testing experience, rather than adjusting question difficulty in real time. This fixed structure is what allows the score report to compare your results directly against other UWorld users.
