Sounds like you are in or just started undergrad. Like was said above, the goal right now shouldn't be ortho, but rather first getting into med school. Basically to do that you need to take general chem, organic chem, physics, biology, calculus, crush the mcat, and get lots of A's in school and do lots of volunteering and stuff like that - but really the first thing you should do if you're serious about it is talk to your guidance counselor, or some schools have a pre-med person. they'll get you pointed in the right direction. oh yeah and stop wasting your time on nerdy sites like this and party it the f-up, college is all about the keg stand, baby. )
