If you no longer need a class, follow these steps to delete or archive it:
Enter ubbu.
In the class you no longer want, click the Options arrow in the upper right corner.
Choose either Archive or Delete.
Note: Deleting a class you permanently lose access to the lessons that have been taught as well as all student accounts associated with this class. All teachers will no longer have access to it.
When archiving a class, you can always unarchive it later. To do this, click on your profile, and then choose the Archived classes tab.
Then, simply choose Options and then Unarchive.
