Quantitative Skills

Students must take one Skills course in English or French, either in S1 or S2 (24 hours).

Students may obtain a waiver for the skills course upon presentation of the appropriate justifications (transcripts, syllabi and a letter of explanation either in French or in English) before course registration. This decision will depend on the nature and number of relevant courses already taken, as well as the grades and credits awarded. Students who obtain a waiver for the Skills course will attempt 4 fewer credits and therefore must take and pass an additional course (4 to 6 ECTS) within the list of "Optional" courses in order to make up for these missing credits.

If you wish to obtain a skills waiver: Please complete the skills waiver request form using the link below. The deadlines for submission are as follows:

Fall Semester Deadline: before June 15th, 2026
Spring Semester Deadline: before November 23rd, 2026
