I currently am a high school student who is interested in pursuing a career in astrophysics/astrodynamics (anything to do with bodies in space and their movements, celestial mechanics I guess). I was wondering what courses/classes should I take in high school and college to pursue this career. I would also like to the know the basic concepts that I would need to know. Right now, I know a little bit of calculus and physics which I assume are a must. Recently, I got a book called The Fundamentals of Astrodynamics by Bate, White and Mueller. I understand quite a bit of the book but I'm not that strong with vectors and vector calculus. So if you guys could tell me what classes I should take and what concepts I should master, that would be great. :) Thanks for your help.
