What is the USMLE and how many steps does it have?

The USMLE (United States Medical Licensing Examination) is a three-step examination for medical licensure in the United States. It assesses a budding physician's knowledge and application of key concepts, principles, and fundamental patient-centered skills that constitute the basis of safe and effective patient care.
Step 1 evaluates the first half of medical school, those mostly non-clinical years that focus on the foundational scientific knowledge that informs clinical practice. In my medical school they told us that time would prove half of all we learn is wrong, the only problem is they couldn't tell us which half. Step 1 tests both halves! This exam assesses basic science knowledge. Many students take this after their second year of medical school and it serves as the bridge to clinical rotations. My suggestion is to build around pathophysiology, pharmacology, and microbiology. Why? Microbiology is mostly you-know-it-or-you-don't, it integrates antimicrobial pharmacology, and there's easy points to be had there. Pathophys and pharm, on the other hand, integrate NORMAL anatomy, physiology, molecular biology, biochem, etc and in learning what is wrong you also, by definition, must understand normal.
Step 2 assesses Clinical Knowledge (CK). This is the step where you translate basic science into clinical practice. You have to master getting to the right diagnosis, and how to get there (i.e. knowing the next step in the work-up). The key to this step, I feel, is by starting at symptoms and learning frameworks that help you move from symptoms to diagnosis. This is where you start with "big buckets" such as "fevers can be infectious, rheumatological, malignant, or medication-induced" and then knowing how to work through differentiating those. What signs or symptoms suggest one over the other? Then, when you know the big bucket, you further differentiate until you reach the right answer. Typically taken during the fourth year of medical school, earlier in the academic year, around July. Study tips: Practice clinical vignettes, build frameworks, and practice them.
Step 3 assesses the ability to apply medical knowledge and understanding of biomedical and clinical science essential for the unsupervised practice of medicine. Taken after graduation from medical school, usually during the first year of residency though some people choose to take it during MS4 year. Some programs may not allow that. If you are in internal medicine or family medicine, consider taking it as late as possible in your PGY1 year as every day is a study day given what we do for a living. Study tips: Focus on patient management, diagnosis, and treatment, and use practice cases. Make sure you practice the free-response questions.
