I'm currently entering my senior year. Anyway, I really think math is taking it's toll on me. I get very stressed out from mathematics and I truly think that one of the only reasons I don't quit math is because I have put so much time and effort into it. One of my main problems with math is just how it takes so much committment. I have given up a lot to become a good math student. I probably spend 20-25 hours studying a week, and add together the 15 hours in class, i know that's only a 40 hour week, but it's just draining. I am completely exhausted. I'm currently taking 3 research projects and 3 undergrad courses (1 advanced seminar, measure theory and a regular course in topology). Maybe I'm just overwhelmed by my workload since it is pretty insane for an undergrad. But my whole plan was to challenge myself as much as I can during undergrad, specifically with research so that grad school isn't too big of an adjustment for me. Perhaps i'm just talking because it's been a long long year. Last year I took 12 math courses, went to an REU for math and then did an independent study for the rest of the summer at my school. That adds up to over a year straight of studying constantly. Then entering this semester, i'm taking the above mentioned schedule and need to study for the GRE and GRE math exams. I feel absolutely overwhelmed. When is it time to really quit? Also i'm going to apply to grad school just to keep my options open. I heard if you don't plan on becoming a professor that lowers your chances of admission. If I don't quit math, I really want to get my PhD and work for a hedge fund or get a financial math masters. Also, how difficult is it to get into a top 10 university for PhD? In general, if I'm not the darling of the math department at my undergrad, do I have a shot at schools like Princeton or Stanford? What about Columbia or Cornell?
