What is Course and Option Selection (COS)?
Course and Option Selection (COS) is designed for students heading into their third and fourth years of study. COS refers to a period in the Winter term where the Registrars Office collects data on students course preferences for the upcoming academic year. Students are guaranteed a space in the courses they choose during COS (i.e. stream selections, technical electives, capstones) so long as it is not listed as a limited enrolment technical elective (see question below for further information on this point). If you change your mind regarding your course selection after COS has closed, you will be able to adjust your schedule yourself via ROSI. Please note that course selection on ROSI is subject to space availability and scheduling constraints. If you choose to make adjustments to your schedule, please ensure you are adhering to your degree requirements as outlined in the Academic Calendar.
