The third and fourth years consist of clinical rotations, sometimes called clerkships, where students see patients in hospitals and clinics. These rotations are usually at teaching hospitals but are occasionally at community hospitals or with private physicians. Mandatory rotations in third year are often obstetrics and gynecology, pediatrics, psychiatry, family medicine, internal medicine, and surgery. During the third year, medical students take Step 2/Level 2 of the medical licensing boards. Fourth year rotations typically allow students to choose several electives and finish required rotations. It is also used as a period of auditioning for residency programs.
