So, my present situation is that I dropped out of highschool following the end of my junior year at the end of last year, got a GED, and am attending a community college this coming September. I took the AP calc and physics tests and did pretty well on them and I've been studying a linear algebra based multivariable book over the course of the past couple months. In order to compensate for the lack of a major physics curriculum at the community college, and to satisfy my thirst for physics, I want to study the major modern books on classical theory. ie Jackson's electrodynamics and anouther major book for mechanics (I haven't heard what the cardinal one for this field is yet), and I need to know what level of mathmatics I need in order to start tackling these. I don't want to launch into them and have the experience soured by a fundamental lack of mathmatical knowledge. Also just as a side note, what is the cardinal text for QM? I figure I would like to tackle QM and GR as soon as I know that i have a solid footing in the classical theories.
