To add one or more new users to the class/group, select the purple button in the action column. A pop-up window will ask you the type of user you would like to add (student user or staff user). The students are broken down into academic levels for easier filtering. You can select more than one group of users, by selecting one or more checkboxes at a time.
Once you have filtered the users by type a list of names will appear. You can select all users or specific users, by selecting one or more checkboxes at a time. Select Add User(s) to place the users in your class/group.
