thanks for the info. But do i have to do stage 1 within the first year?
Well yes, all the MATH1XX1 courses as listed in the handbook are taken by students in their 1st year, but MATH1081 can be done in later years if you wish, although I would recommend for you do it first year
NOTE that MATH1081 is only a recommended course, so you if find that you do not want to do it, you can always replace it with some other Free Elective or Gen Ed of your choice, as long as it still fulfills your program requirement.
