3. Course visibility

Courses can be hidden from students at any point before or during the semester. This setting is located in the course settings. When visible, students will be able to access the course. 

Navigate to the "Settings" tab on your secondary navigation bar and find the "General" section. There you will see a setting "Course visibility" which you can toggle to show or hide from a dropdown. Click "Save and display" at the bottom of the page to apply settings.
