I know upper-year maths will require MATH 1A03/1AA3 and Math 1B03.
You might want Math 1MP3, because there are a lot of cool upper-year applied math computing courses that you'll want to take.
Stats 1L03's course description on the website confuses me, because it talks about serious things, whereas when I took it the class was a complete and utter waste of time.
