For example, a Biology course that has an extra meeting time per week for a Lab, or perhaps an Enrichment class that meets all but one day out of the rotation.

Schedule Exceptions will carry through the subsequent Terms left for the Course for the Academic Year. The following Academic Year, if you use Schedule Set in Master Rollover, the Schedule Sets with Exceptions from the previous Year will copy over into the new Academic Year.

If instead you choose to import your course enrollments, you'll need to manually create your Schedule Sets and Exceptions for the new Academic Year.
