There are two ways to test run a course.
The first way is to use the Preview function. Navigate to the course that you want to preview, then click on Launch Course Preview at the top right.
The second method, which we recommend, is to enroll yourself in the course and use the Admin/Learner toggle.
Now simply click My Learning then click on the course that you want to preview. This will let you preview the course as an actual learner, showing you exactly what your learners will see.
