I'm at a decent university(Manchester university) know I can get first. Got 70% in first year even through I failed a course because it was stupid matlab and refused to do it, if I did would have got 80%(read book about Grothendieck that strongly influenced me, which probably hurt my grades through). The problem is my second year grade is 63% because I was depressed as hell last year(family problems). I know I can get 80%> and if I choose the subjects I'm really good at could get 85%>. The problem is my social life goes down the drain, plus the subject I really want to be good at and study is category theory. I spent a lot of time reading books like conceptual mathematics, Serge Lang Algebra and other book on category theory. Feel be waste of time trying to read hard books if want to get high grades. The problem is I fear that I'm going to be judged on stuff like how well I can differentiate or how fast I can do algebra or worst how well I can memorize definitions. It's very painful as I feel like I'm not even learning stuff. But, with my grades even if I'm better at Maths then everyone else at my uni I'm going to get rejected. So yeah can get high grades. Just mean, stop learning stuff that isn't going to be on the exam, rote learn the definitions everyday, rote learn all the proofs and go over the example sheets n times a day. The sad thing is I doubt I will have greater understanding of Maths, which is all I really want. My social life is probably going to be non-existent now so got time to study. Just feel like should I grind to get 90%> or learn something that I actually care about and am interested in. The joke I don't even care about money as have very little social life and never want a gf. But, it would be distracted as hell if I had to get a normal job, which I would be forced to do. So doing 2 years of stuff that I consider pointless looks worth it to get high grades.
