Option 1
Give students a permission number to override a closed class using the Closed Class checkbox on the Class Permission page. This option allows you to give permission to wait-listed students, when appropriate. To determine which students need permission, the wait list will be available to you until the end of the add and drop period.
Option 2
On the Enrollment Control tab, uncheck the Auto Enroll from Wait List checkbox, which changes the Enrollment Status to “Open” and allows any student to register for the remaining seat(s) up until instructor approval is required.
