I have recently learned that a class that I need for my major is full and so am considering taking physics for pleasure. My only dilemma is that I cannot afford to let my GPA slip if I could not perform to standard with the mathematical applications involved. I have never taken physics before and do not know what to expect. I just have become a bit "obsessed" reading until the wee hours of the morning, and have come to the conclusion that formal education is necessisary to really grasp the concepts. However, it may be a bit foolish to pay for instruction when it will not be applied to my career path. So... any advise or really awsome websites or books that introduce all of the physical laws? Thanks.
