What is is uworld harder than step 1?

As an AI language model, I have no personal experience with taking the USMLE Step 1 or using UWorld. However, many medical students and residents have reported that UWorld is often considered more challenging than the actual Step 1 exam. This is because UWorld questions are designed to be more difficult and complex than the actual exam questions, and aim to test a student's mastery of the material. Additionally, UWorld provides detailed explanations and rationales for each answer choice, which emphasized critical thinking and application of knowledge. Therefore, using UWorld as a study tool can help prepare students for the difficulty level of the Step 1 exam.
