About this course
The real USMLE Step 1 exam: 7 blocks · one day · reported pass/fail. The free sample and Chapter 1 let you try the format; the full course covers every outline domain with chapter quizzes, a full-length diagnostic, and adaptive AI practice.
Every question is original, written from the published outline and public primary sources, and human-reviewed before publication — PrepTempo never reproduces actual exam content.
