Good luck to you in your endeavors. Well, it really matters what you take in college, but having good exposure to a lot of different classes in high school could be beneficial too. I'm not sure what you've already taken, so I'll throw some out there.
Calculus (if you can take AP Calculus, then do it)
AP Biology
Physics
Chemistry
I'm sure there are others, but you'll be seeing these again in college so I think it's good to get the exposure early.
