Choosing your preferences
For each of your units you will have a series of classes visible in CAS. Each class will have several timeslots available for you to choose from and you should choose at least four preferences for the times that suit you best. Allocate a preference of 1 to your most preferred timeslot, 2 for your second most preferred timeslot, 3 for your 3rd most preferred timeslot and 4 for your 4th most preferred timeslot.
The percentage next to the preference dropdown indicates how popular each option is. Choosing a less popular option will improve your chances of getting your first preference.
It doesn’t matter if you login as soon as CAS opens to enter your preferences or a few days later, everyone gets an equal chance at receiving their first preferences.
Once the period for choosing preferences close, CAS sorts through the preferences to generate the best timetables available for everyone.
