Courses may have expiration dates set where the course must be completed by a certain day which is often set by your supervisor. You can see if a course has an expiration date a few ways.
On the My Courses page there will be a countdown saying how much time is left.
If you open the course the expiration date will appear in the Course Information section.
Once a course has been expired the Take Course button will not appear and the countdown will be changed to EXPIRED. You will no longer be able to take the course. If you believe this was done in error, or if you would like more time, we recommend that you contact your supervisor or contact us directly.
