Most medical schools require a minimum of 1 year or biology, inorganic chemistry, and organic chemistry. All of these courses must include lab, which usually increases the credit hour of the course. Some medical schools may require additional hours in science courses, so it is important for students to know the specific requirements of the medical school where they plan to apply. At most universities, students usually complete these classes as a junior or senior. If a student is a science major, these courses will be required to graduate from the program.
Most medical schools require English courses as a prerequisite. According to Harvard medical school, writing is a very important component for studying and practicing medicine. Usually English is a prerequisite for college and major requirements so many student complete a year in English as a freshman in college. It's okay if a student doesn't complete it the first year, but it will be important for applying to medical school.
Most pre-med students in college choose science as a major, although it is not always required. As a science major, they will need to complete at least one course in physics. Physics is also a prerequisite for some medical schools. Even if students are not sure that the school will require physics, it is good to complete a course, as it looks favorable on their application.
Depending on the college major, some form of mathematics will be required for graduation. As a preparatory course for medical school, many medical school applicants need an introductory class in calculus. Unless a student is majoring in a science or engineering field, calculus will less likely be required by the undergraduate program, so an early decision to attend medical school is crucial for completing the calculus requirement by the application deadline.
