Hey all, I'm currently attending the International Baccalaureate Diploma Programme, and I'm probably going to study Physics when I start College (a little less than two years from now). I'm just wondering whether there is something I should/could start doing now. Any good books? Any suggestions as to which topics I should work extra hard on in High School? Physics Higher Level is built up of a Core curriculum, and several options from which I can choose. I think I need to choose 2 or 3 options, so knowing which topics will be most useful for further physics studies will help me with that choice as well. Thanks. Edit: Right, two options it is. I need to choose two of the following topics: Astrophysics Communications Electromagnetic Waves Relativity Medical Physics Particle Physics Any tips?
