When would be a good time to take physics? Should I take one semester at the end of my soph. year and one semester at the begining of my jr. year? Is it a bad idea to take to the full year the year I take MCATs (i.e. MCATs in April, but school's out in May)? First semester of physics at my school is 5 credits, this would mean my whole schedule (sophomore year) will be science courses, org. chem, & bio course(it's my major).
