I'm currently about to finish (next week!) my lower division physics classes and move on to the upper division courses while transferring from a junior college to UCLA. I feel utterly and completely unprepared for what lies ahead. I feel like the textbook we used (Fundamentals of Physics, 9th Ed) grossly oversimplified the mathematics that should be used for these courses. Is this a normal feeling since I'm transferring in the Fall and I have no idea what to expect, or should I really be worried? I'm going to work through Boas' Mathematical Methods in the Physical Sciences book over the Summer with my fellow physics majors, are there any other books you would recommend reading / working through before moving on to the upper division courses? Thanks!
