There is also no guarantee that the minimum required course credits can be sustained from term to term in Part-time Studies. Students who require a minimum course load to retain eligibility for financial aid or international student status have no guarantees that PTS courses will be available. Please contact the department for course planning: NOTICE: Many required higher-level and elective courses may not be offered each term and some PTS courses are only offered once per year. COMP PTS courses have specific prerequisites, and these must be completed in the correct order.
