How much math and physics will I have to take? I don't mind taking some courses in these areas, since I already am, but I'm not sure how many I should be taking. Will it have to be very high level math or physics? More what I'm asking I guess is, what specific types of courses would be the most beneficial to take, and how long would I have to spend in each one(estimates are fine, I don't expect anyone to know exactly how long it will take)? Thanks in advance for any help/advice I get.
