I am wondering how absolutely necessary it is to know mathematics if I am to study physics at a University. The ordeal I'm having is that perhaps 2 years ago I finished a sequence of courses in Mathematics, being Calculus I, II, III, Differential Equations, and Linear Algebra. After quite the long break from school I assure you I can remember none of it. I've had Physics courses, but none that touched on Calculus very strongly, so I'm really asking: Will starting in Calculus-based physics while not remembering any of it be anything short of detrimental? ..or should I take Calc II and III again at a smaller college while I'm waiting on my University apps to be accepted?
