How to understand whether the latest revision of the lesson/assignment has been published. Course draft.  
When you design a new course, it is not published by default: a crossed-out cloud icon is displayed next to the course name (or in its place if the course title field has not been filled in yet). The same icon will appear if you unpublish a ready-made course.


If the course is not published, regardless of its settings, the students and the instructors cannot see it – it is a draft. 

To publish a prepared course, go to the course settings to the “Actions” tab and click on the “Publish” button.

Upon publication, the course becomes available in accordance with the settings you specified.
