If I were just starting college now and knew I wanted to be pre-med, here's how I would set my schedule:
First year:
-physics w/ lab
-gen. chem. w/ lab
-calculus (if you haven't taken it; ideally, you should take it as a high school senior. If you already have taken calculus, take statistics or differential equations instead.)
-English
-some elective (foreign language, psychology, philosophy, anything else that has nothing to do with science)
Summer after first year:
Try to get some clinical experience. I worked at an Easter Seals camp that summer. Or, go study abroad; I did that the summer after my second year and it's a great experience.
Second year:
-organic chem w/ lab
-biology w/ lab
-research hours (ask one of your science profs whose class you liked and whose subject you are interested in. You'll probably start out washing glassware, but if you stick with it for a few months and they see you're serious, you'll start getting to do more interesting things. The biggest problem we have w/ undergrads in the lab is that they are not reliable, so you can make a big impression just by being interested and showing up when you say you will. Plus you might eventually even get paid, and you'll get a great LOR for down the road.)
-nonscience electives or other classes you need for your major.
Summer after second year:
-biochemistry with lab
-study for MCAT (take in August)
I know that a lot of people like to put off taking physics, but I believe that you should take it as a freshman if your high school math background is strong enough (pre-calc. or beyond). You can take calculus concurrently with calculus-based physics. I think it is better to take calc-based physics if at all possible rather than taking non-calc-based physics because it's a more rigorous course; that's the class the physics majors take. I took calc-based physics as a freshman, and it worked out great. When I was in my gen. bio. class and the prof. was talking about how cell membranes function like capacitors, I was the only one who had any idea what he was talking about! Plus, it is a logical sequence, because calculus is the basis for physics, physics is the basis for chemistry, and chemistry is the basis for biology. Taking biology first is a**-backwards, IMHO.
