Sorry for the long title, but I just received some of my marks for the semester including a C+ in a programming course and F in a cell biology course) and am worried that have ruined all my chances at getting into summer program (I'm in Canada, so I'm looking at the few US REUs that accept foreign students on a limited basis).
What should I do if I don't get into any summer activity to help my graduate school application if I want to pursue mathematics? I'm in second year and haven't taken too many higher level maths courses, so I don't know how that would look when applying for NSERCs at my school.
I was thinking of maybe just doing some reading in mathematics and working on some personal projects that may help me look like I can actually do something on my own. I am also currently self-learning combinatorics and graph theory in the hopes of working with my discrete maths prof who does combinatorial optimization (and has asked and received my CV already).
If anyone has any advice as to what I can do to enhance my grad school application if I get rejected from everything I apply to? I feel ridiculous for doing badly this semester as it was just too much to handle and doesn't reflect my work ethic at all. I want to redeem myself but don't know how? Thanks in advance for the advice!
