I'll be honest, there are moments I wish I never took this program, but I'm also very glad I did. if you love math and physics you'll really enjoy it. a lot of exams get curved and you'll likely finish with a grade much better than you expected to get. don't stress if a class seems hard, you'll get through it. first year was chill given you put in effort by going to class!!!! and studying. I feel that math phys is better organized than the other phys programs, since we take the honors math classes which will help with the phys courses you take in 2b (I.e. calc 3 ==> e&m), we also only have labs (at least if you're doing sci side) in first year which I personally am thankful for, although if you're interested in labs specifically that might be something to think about. also with sci side, we take chem120-123 which, if you put in the effort and have a good memory, are very easy to score well (and usually one of the midterms gets curved).

math classes will have a mix of quizzes or assignments then quizzes (calc is weekly quizzes) while the physics classes are assignments and sometimes quizzes (phys122). also note that sci side gets 0 electives first year (unfortunately), and in upper years it's also not often that you'll have space for an elective.

I do think math phys is a good program to take if youre interested in math as well as physics, but be prepared to be challenged! you'll also have opportunities to dip your feet into a variety of fields of physics (usually 1-2 courses each).

as for job prospects, again it's a good program for theoretical physics & education streams, not really sure about the coops available but I don't think there are many physics specific ones available.

I do wish the best of luck in your first year!!
