Missing the CAS allocation date
If you are a first round TISC offer student or an existing student and don't enter your class timetable preferences before the allocation date, CAS will automatically allocate you into classes. You can continue to edit your allocations for approximately one week after the allocations are released and again from approximately one week before semester begins (if there are any spaces available in classes). You can continue to make changes to your allocations up until the time CAS closes (approximately two weeks after semester begins).
Check the CAS website for specific dates for when you can enter preferences, see and edit your allocations.
