You have to take both semesters of physics, the same way you have to take both a year of inorganic and organic chem and the other requirements for pre med. Most schools have general lectures for non majors and seperate tracks for majors, but there isn’t that much difference. The reason is obvious, they want to see if someone has the ability to handle the kinds of learning required in med school, and Physics and Chemistry are involved in the functioning of the human body, not to mention that the chemistry in our bodies is based in what we call Organic chemistry. Doesn’t mean that someone who does well in these classes will be a good doctor, but someone who struggles with these courses isn’t going to handle what you learn in med school and as a doctor very well…
