Last Day to Enroll in a Summer Course: June 27
The last day for summer class enrollment and course changes (drop/add) is Monday, June 27.
The last day for withdrawing from courses without failure by default is Wednesday, July 20.
Please note, the Student Experience team cannot enroll students in a closed section of a course. We encourage you to monitor mosaic as students can switch their schedules and courses until June 27. If your preferred course or core opens up, then you may enroll in it at that time. There are no wait lists for Commerce classes.
