General information on course sequences

The course sequence you need to follow is that of the year you first joined your program. For example, if you were admitted into your program in the fall of 2021, you must follow the course sequence of 2021-2022.

Please note:

  • Some courses are not offered every term.
  • Courses at levels 1000 and 2000 are offered in French and in English.
  • Some courses at levels 3000 and 4000 are not offered in French.
  • For the French course codes, refer to the French course sequence.
  • Courses with fewer than 10 registrants may be cancelled.
