Special Sessions

What They Are

While most Main Campus classes meet for the entire fall or spring semester, some classes are better suited to a shorter timeframe. Departments may choose to offer those classes in a special session.

Special sessions occur during the regular fall or spring semester, but last for only five or eight weeks. Since special session classes start and end on different dates than full-semester classes, their add, drop and withdrawal deadlines also differ.

When registering for classes, pay close attention to the name of the session (e.g., "ÌÇÐÄVlogÆƽâ°æ Campus 8-Wk Session 1") and the class's meeting dates (e.g., "2022-01-10 through 2022-03-02") so you know what to expect.

Special Session Dates Are Unique

Special session add, drop and withdrawal deadlines do not match the full-semester deadlines. If you're taking a special session class, it's your responsibility to familiarize yourself with that session's academic calendar.

What to Watch Out for When Dropping a Class

Each session's dates and deadlines are unique, so you need to take extra care when changing your enrollment. 

Each session functions as its own semester, meaning if you drop all of your classes in a given session (even if it was only one class), you've technically withdrawn from that session.

Before dropping a class, carefully review the special session calendars to make sure you understand the financial implications of that change.
