Most medical schools organize their training into two parts. Basic science training usually occurs during the first two years of medical school, when you learn about basic medical concepts, the structure and functions of the body, diseases, diagnoses, and treatment concepts. You’ll also learn the basics of doctoring, such as taking medical histories and other essential competencies. The last two years of medical school will involve clinical clerkships, during which time you will receive basic instruction and hands-on experience with patients in the major medical specialties.
