If you accidentally set a class end date or would like to recover your students after they were removed on the class end date, you can restore the class from the Class tab.
On the Class tab, select the Class list drop down arrow (upper left).
Select Restore Classes (bottom circular arrows). You will then be able to select any of the classes that have ended due to Class End Date. Once you select the class you would like to restore, select Continue.
You will then receive a confirmation that the class has been restored.
