I messed up last year and got a 6 in math 1aa3, i didn't mind very much since i wasn't planning on getting into any math program.... anyways now i have changed my mind so I wanna switch into one but the one i want requires a 7 for 1aa3...
is there any chance they will be flexible here? I'm taking 2x03 now and i'm most likely gonna get 10+ in that.
it would be silly to keep me away from the program because of a first year mark when i have already showed i can do much better in second year, amirite?

in my experience, if you better in the second year counterparts, that's fine... best to check with academic advisers though

you should be fine, talk to academic adviser.
