I am a non-traditional pre-med. I am 35 years old and concerned about spending too many years on pre-requisite courses. I need to decide what pre-reqs courses to prioritize.I have seen that each medical school has its own list of pre-requisite coursework. For example some schools require 1 semester of stats while others require one year of math including calculus. Some require genetics , while others don’t. My question is : Can I apply to a school if I have some but not all of the listed pre-req’s for that particular school.
