Getting quality USMLE practice questions is key for exam preparation. This page provides free samples from top USMLE question banks to help you get an idea of what to expect on test day.

What is the USMLE?

The United States Medical Licensing Examination (USMLE) is a three-step exam required for medical licensure in the United States. It assesses an examinee’s understanding of and ability to apply concepts and principles that are important in health and disease.

The USMLE is sponsored by the Federation of State Medical Boards (FSMB) and the National Board of Medical Examiners (NBME). It is divided into 3 Steps:

  • Step 1 – Assesses whether you understand and can apply important concepts of the sciences basic to the practice of medicine. Step 1 is taken after the second year of medical school.
  • Step 2 CK – Focuses on whether you can apply medical knowledge, skills, and understanding of clinical science essential for the provision of patient care under supervision. Taken during fourth year of medical school.
  • Step 3 – Measures whether you can apply medical knowledge and understanding of biomedical and clinical science essential for the unsupervised practice of medicine. Typically taken during first year of residency.
