I am applying to USC this fall with my primary major as Biomedical engineering. I am a little unsure with what my alternative major should be (looking for something easy that could get me into USC and has the possibility of transferring). As of now I am considering Environmental Science, Global Health, or Health Promotion and Disease Prevention Studies. I plan on going to medical school. Which of these majors is easiest acceptance to USC? Are there any others? Can you transfer from Letter and Science to Engineering?
