You can use item permissions to manage access control for your items like courses, tests, folders and other.
If you create an item, you automatically become an owner of that item and gain full (edit) permissions.
If you have edit permissions on the item, you can manage who can view or edit the item using permissions settings.
Examples:

For example:
This setting always override item-level permissions.
