Instructors or course editors can temporarily switch to a different role to view the course from that perspective. To see the course as a student would, use the Role Switch widget and select 'Student'. This allows you to experience the course exactly as a student would.
The role switch functionality is also available by clicking on your name at the top and changing your role. Select your name again and click on the X next to the role to cancel.
Note: You cannot submit tests or assignments that display in the gradebook as a Student using Role Switch. See Impersonate a Demo Student for this functionality.
