Some courses will have a due date. This date is when the course is due, and depending on the settings, you might be locked out of the course if you don't pass it before then.
It is a good idea to check your courses for due dates to make sure you don't miss anything. Checking if a course has a due date is simple.
First hover over Training in the navigation bar, and select My Training.
Next, select the course you want to check for a due date by clicking on its title.
Once you've opened the course you can find the due date displayed next to your Total Progress bar and Total Time, as you can see underlined in red in the screenshot below. In this case, this course is due for completion by May 1st, 2021. If a course does not have a due date, that area will be blank.
If you are past the due date for your course and find yourself locked out from completing it, you will want to contact your administrator or training manager for help.
