A Preview Learner can only be added to a course by a key user. If you want to use a Preview Learner, ask your key user if they can add it to your course.
Once the Preview Learner has been added to the course, go to the Classlist and search for the Preview Learner.
Click the arrow next to the Preview Learner, then select Impersonate and click Yes.
You are now logged in as the Preview Learner. You can see this in the top right corner by the icon. From this spot, you can also stop impersonating by clicking on the name and then clicking the cross.
