Hi David,

Welcome to OLT. :)

Any Lesson that you have started will save itself to the last page you answered, and ask if you would like to return to that page - should you re-enter that lesson after having left it for any reason.

Any Quiz should be completed before you leave it, however many quizzes will allow you to save your work without submitting if you get called away, and then come back to it and pick up where you left off.

Final Exams should be completed in one sitting, and without using any aids.

In any event, any work that has been submitted, is already saved.  The system logs the beginning of all lessons and quizzes, but will only record work that you have submitted.  Any time you click on a button within a lesson or a quiz - unless it says otherwise, your work is saved to that point.

Please let us know if you have any further questions.

Sandra King.
