How to delete a course
To delete a course, either published or unpublished, you will need to do so lecture by lecture.
Login to your account => click Courses => Edit the course in question => scroll down to the first lecture and click the delete button => do this for all the lectures in the course.
After deleting all the lectures, delete the course section as well.
For a published course, after deleting all the lectures, move to the tab named publish and unpublish the course. Then, go back to the lessons tab and delete the course draft.
You can also unpublish the course before deleting it one after the other.
Please note that deleted courses cannot be reclaimed. You will have to start the process all over again.
To avoid mistakenly deleting your courses at a go, provision has been made to only delete them one lecture after the other.
