The United States Medical Licensing Examination® (USMLE®) is a three-step examination for medical licensure in the United States. The USMLE Step 3 is a 2-day computerized examination with approximately 500 MCQs, as well as computer-based case simulations (CCS) which assess your ability to evaluate history and physical exam information, order diagnostic tests, select initial therapies, and manage the patient. The USMLE Step 3 primarily focuses on patient management (45-55% of questions). Other topics include history and physical; lab and diagnostic studies; diagnosis; prognosis; and pathophysiology—each consisting of about 8-12% of the exam questions. Also, each question falls into one of three clinical encounter frames: initial workup; continued care; and emergency care. The test is administered by appointment on a year-round basis.
