Course Drafts allow instructors to prepare courses more thoroughly and save any changes in the draft until they are ready for publication.
When creating a course with Course Builder, at the top right corner check the option "Make Draft" in order to save the course in a draft format.
Also, you can change the status of the already published course.
Courses saved as drafts won't be displayed in the search results on the website, and if the user tries entering the course page, it will notify the user that the page doesn't exist.
Please note if you enable the Course Pre-Moderation option when publishing the course it will have a Pending status, meaning the admin has to approve it. Only after approval, the course will be visible to students.
The course is marked as drafted (instructor's page):
