I know my post is vague, but perhaps someone can help me. I have finished my college Calculus series and will take Differential Equations next. I have done well in all my courses, but still feel like I'm not really grounded mathematically. Perhaps a Physics course, to demonstrate more applications? I asked a friend in Grad. School, who said that math as a whole starts to make more sense once you take an analysis course. A physicist I know said that some Statistics courses would help. What do you think?
