UWorld vs AMBOSS for Step 1: Choosing a Question Bank
UWorld and AMBOSS can both support Step 1 preparation. The choice is less important than using one deliberately: complete timed and untimed blocks as appropriate, review why each answer is right or wrong, and turn recurring misses into a targeted next step.
Current platform differences
UWorld now includes its Medical Library, ReadyDecks, UAsk AI, and a study planner in certain plans. AMBOSS combines a Qbank, library, and Anki integration. Both product lines change, so compare the plan you are considering rather than relying on old screenshots or question counts.
A library can be useful when it answers a documented question from review. It can become a distraction when every missed item triggers a long reading detour. A question bank is useful only when the explanation changes what you will do on the next similar question.
What the research can and cannot say
Burk-Rafel and colleagues surveyed 274 students at one medical school during 2014–15, when Step 1 used numeric scores. Practice-question volume was associated with scores after covariate adjustment, but the adjusted R² of 0.56 describes the entire model, not question volume alone. The observational study cannot establish that a particular Qbank, a fixed volume, or more questions cause a higher score.
Use that finding as a prompt to make question review intentional, not as a quota. Track error types, choose a limited follow-up resource, and return to new questions that test the same concept.
A simple decision rule
Choose the platform whose interface and explanation style you will consistently use, then give it a defined role for several weeks. Reassess from your review notes and current standardized assessments, not from a universal readiness percentage. If you add the second bank, name the gap it fills; do not use it merely to create more unfinished work.

Try ten representative questions before committing. During review, ask whether the explanation explains your tempting wrong answer, whether reference use stays focused, and whether you can name one next action. A second bank should have a defined role—fresh questions, another explanation style, or a narrow gap—not merely add unfinished volume.
