From experienece, are these two courses really important to someone looking to major in physics? I've read the "So you want to be a physicist" guide, but if I work with the book Mathematical Methods in the Physical Sciences, will it be enough to make it through the upper level physics courses (as opposed to general physics)? I'm currently taking discrete math but I find the proofs extremely boring. Though I seem to do great with the applications in calc & calc based stats that I've taken. So I'm just curious as to if I should bother taking Linear Algebra if its just going to end up being more proofs. Also besides differential equations, are there any other math courses I should be looking to take that would be helpful down the line? I would eventually like to go to grad school as well, if that factors in at all.
