How do I enrol students or manage access? 

Open the course, select Participants, and use Enrol users to find users and assign the appropriate role. Start and end dates can be available depending on the enrolment method and your permissions.

Use the Participants menu to review Enrolment methods, including manual enrolment, self-enrolment and externally managed methods. Suspend access when participation should be retained without current access. Unenrolling a user can affect access to their course data, so follow local policy before removing enrolments.
