Unlike some of the other health professional schools (e.g. Physican’s Assistant schools), medical schools are less demanding and more consistent in their course requirements. They require an introduction to multiple science disciplines but do not require specific medically related courses (e.g. human anatomy, human physiology). Consequently, they are happy with students that have majors outside the sciences. To be accepted into medical school, you must excel in these introductory science courses and also in the courses of your chosen major.
To apply to nearly all medical schools, you need to take:
General Biology I and II
General Chemistry I and II
Organic Chemistry I and II
General or Analytical Physics I and II
Two English courses (our freshman year critical writing course counts as one)
At least one Math course (a few schools specifically require calculus or statistics)
Biochemistry is now a component of the MCAT exam, and a few schools actually require the course at the present time.
Similarly, the new MCAT exam includes components related to introductory psychology and sociology, but most medical schools do not actually require specific courses.
