Just to give you an idea of the timeline.... you will have to complete college with a bachelor’s degree as well as all of the Pre-med requirements (1 year biology, 1 year inorganic chemistry, 1 year organic chemistry + labs, physics, calculus, and biochemistry). GPA should probably be 3.5 or better (preferably >3.8). You will also have to score well on the MCAT. Once accepted to medical school, as long as you pass your classes and perform reasonably well during your four years of medical training, you can apply for a general surgery 5 year residency. Following that, you will apply for a 2 year trauma surgery fellowship. This career path requires 15 years of school after high school.
