Course level permissions compose the third level of permissions, below system and domain permissions but above item permissions. These permissions operate on a single course’s elements outside of its syllabus, such as files, CV information, and which groups should be correlated with guest and public access for that course.
Most course level permissions are based on a particular group (such as instructors), and can be accessed by going to Settings > Group within a course.
Setting which groups should be used for guest and public users is found at Settings > Course.
