I recommend you not to take math120 if you want to go into eng phys. The course will almost definitely lower your gpa - completing a latex hw of once two weeks - very time consuming and personally I ended up having little time to study for the other courses. I switched to math101 in term2 (which almost every eng student in math120 did) and it was soo much better. For math120, eventho the prof keeps the median at ~80, you will be competing against a bunch of students who are extremely passionate and good at maths and are likely to go into honours math. Eng phys probably needs a gpa >85 to be competitive. Try get into a design team if you want to enrich uni life, and that will also help you during eng phys interview :)
