When enrolled to a course, a participant receives an email with a course link. 

A participant may also find a link to a course on the Learning portal, on the My Courses dashboard.

While taking a course, a user needs to read the learning material and answer questions in quizzes (if a course includes quizzes). When done with a module, a participant needs to click Mark as completed.

A course will be finished after completing the last module.

After a participant finished a course, they still have access to it on the My Courses dashboard.
