About this exam

The United States Medical Licensing Examination (USMLE) Step 2 Clinical Knowledge (CK) assesses whether medical students and graduates can apply clinical knowledge to patient care. It is taken by eligible students at U.S. and Canadian medical schools and by eligible international medical graduates pursuing U.S. licensure. Residency programs may consider a Step 2 CK result as one part of an application, alongside clinical experience, recommendations, and other qualifications; the exam itself does not guarantee a residency position.

Step 2 CK is a computer-based exam built around clinical scenarios and questions about diagnosis, patient management, and preventive care. Its content spans the major areas of medicine, including cardiology and vascular disorders, pulmonary and critical care, gastroenterology and hepatology, and nephrology and urologic disorders. Preparation involves more than memorizing facts: candidates need to recognize the most relevant findings, choose an appropriate next step, and manage time across question blocks. Check current USMLE materials for the latest exam details.
