You may find you have two classes for different units scheduled at the same time. This can be fixed by selecting another class time for one of the units. 
1.    Login to CAS
2.    Go to select, and look at the options for the two clashing classes
3.    Is there an available class you can move to? 

 

If one of the classes is a lecture, assign yourself to the clashable lecture recording 
1.    Yes: select the available class
2.    No: waitlist yourself for a class that’s unavailable 

 

If you have allocated yourself to the clashable lecture recording option to resolve a clash, you can still attend the in-person lecture in weeks in which you are not impacted by the clash.

 

You can edit your allocations up until approximately 2 weeks into semester, check the CAS website for specific dates.

 

If there is only one class to choose from and one of the units is an elective, you may consider changing your enrolment.

 

If both units are core, option or bridging, and you’re not able to fix the issue with one of the above steps, submit a CAS request form.
