UWorld is a question bank (Qbank) that simulates the actual USMLE Step 1 examination. While many resources exist for Step 1 preparation—such as First Aid, Pathoma, and Sketchy—UWorld is universally regarded as the "gold standard" for testing your knowledge.

This is where you simulate the real test.
