Cyber University courses can be toggled on/off in the Edit Course Selection screen of the Cyber University section of your Admin Portal. Once Cyber University has been activated, all courses will be toggled on by default. You can deselect a course by unchecking the box on this screen.
As soon as you have activated Cyber University and selected the courses that you'd like your users to take, they will be able to complete the active courses through their Training Portals.
If you would like to prompt your Users to complete training, you can Send Reminders at the top right of the Cyber University tab.
