Got math exams back

I got a 92 out of 100 (the average was 84?). I made two stupid mistakes on it. I confused one-to-one and onto, and didn't recognise that a square matrix is either both one-to-one and onto or neither, respectively docking me 3 and 5 points. Honestly, those were some stupid mistakes, and I pretty much deserve to have lost 8 points. Otherwise, I got all the difficult stuff on the exam right. Kinda proud of that. Yep. Pretty proud.
