According to About's Tara Kuther, medical school is both academically and personally difficult because of the large time commitment required. Medical school combines coursework, labs and clinical work, all of which require frequent studying.
The first year of medical school can be the most difficult, as it consists of classes and labs that require large amounts of memorization. The second year involves learning about diseases, also known as epidemiology. Second-year students also must pass the U.S. Medical Licensing Examination to continue medical school. The third and fourth year of medical school involve clinical rotations, where students work with a medical team. They begin at entry-level positions for specialized clinical work in the fourth year.
