On My learning, under To do. Each course shows its deadline.
When your school sets you a course, we email you a link to it. We remind you 14 days before the deadline, and again if it goes past.
To finish an assigned course, work through every module and press "Finish and get certificate" at the end. Your school sees straight away that you've done it. If you've done the course before and your school asks you to do it again, the course shows a Retake button.
If more than one school or agency asks for the same course, it shows once, with the earliest deadline and who's asking.
If you think a course has been set for you by mistake, ask the person who manages training at your school. They can mark it as not required.
