Lesson statuses

Lessons have the following statuses:

• Publication Status: published, draft (saved without publication).
• Completion Status: completed, in progress,not started. Completed: The "Complete" button has been clicked. In Progress: The "Complete" button has not been clicked.
• Success Status: passed, failed. Passed -  the "Complete" button has been clicked. Failed -  the "Complete" button has not been clicked.

How lessons can combine completion and success statuses. For example, if you open a course and click "Complete Course," but within the lesson, you do not click "Complete," then the lesson within the course will be marked as completed but not passed.
