I'm currently at junior at my college and I was wondering how much organic chemistry do I need to get into optometry school, with the biology degree I can either go two paths, either take 3 ochems that contain two labs or take 1 ochem with one lab, also I'm currently taking the first path with three ochems and I'm in ochem 1 and I just took my first exam and I dont think I did well on it, should I withdrawal from class and sign up for the second path next semester?
