I'm on medical leave from University due to severe depression, unfortunately. My grades dipped considerably the semester before this one, due to romantic issues that I simply wasn't able to resolve. My grades that Term where A, two B's, and two C's :(
Really sucks, since I had prior aspirations to get a Ph.D in Mathematics.
I will hopefully be heading back to Cambridge in the Fall to straighten things out.
Entry into PhD programs is normally just based on your Honours project, and not on your undergraduate results.
