I'm starting my junior year in physics after a year out of the system. What do you think are some of the best sources/books/etc for someone in my position? I have a little under two months of time available to me. I've been rereading my college text books cover to cover, and am wondering if there's something else I should throw in there. Still have Physics II, Calc III, and a half of Diff. Eq. left to cover. Anything else I should throw in there?
