I have a friend who ended up being in Health Sci for only three years and then going on to med school. Apparently, it is a rarity to be accepted that early.

I would bank on completing a fourth year. You need really good grades, a high score on the MCAT, and other things...things I don't know cuz I'm not interested in applying to med school and each med school has different requirements.

well to answer this persons question, i also had the same question and figured out that okay the situation u have is the "chems 1A03 and 1AA3" then one more from the life sci list so i pickeed envirsci, so there i have 3 courses from the list and fulfilled 1/2 courses from life sci one course list from admission to level two biochem and biomed. you still need one more which comes out fo your electives so say like (psych, envirsci, or like compsci) will fulfill that. and now you have the prereqs to get in.
