How do I add a tutor to my course?

Any existing student can be upgraded to a Tutor for that course. If the student is not yet enrolled in the course, you can add them from the Manage Enrolments page (here's how). On the Manage Enrolments page, find the student and click the orange "Make Tutor" button next to their name. They will move to the Tutors table at the top of the page. 

To remove Tutor access, find the tutor in the Tutor table and click the orange "Unmake Tutor" button. They will move back to the Students table below.
