There are several reasons why this may be happening. It is important to understand that this is a “time required” and “content required” course. This means you must meet minimum time requirements for each module and the course, or you cannot continue. To get the best experience from your course, be aware that:

Your session will “time out” if you are inactive  for 10 minutes
Module quizzes “lock” if you don’t log out properly or close your browser while taking the exam
Not completing ALL module activities (including student activities, videos and interactions or skipping pages)
Using a browser OTHER THAN: Google Chrome (recommended), Firefox, Safari or Microsoft EDGE (not Internet Explorer)
 
Do you have ANY questions on the above?
