Depending on their types, the courses have different durations. Most courses are available for one year. After that year, the course will be archived.
Once a course has ended it will be closed for new participants after about one month. The course material will remain available up to 6 months after the courses end date. Only those who were enrolled before the course has ended can still access the course material. After that the course will be archived and the course material can not be accessed anymore. It is still possible though to download your certificates gained in the course.
If you weren’t enrolled, it is possible that the course re-starts at a later date. You can add it to your Watchlist, which you will find later on on your "My Courses" dashboard. Please make sure you subscribe our newsletter in order to get the newest information about a re-run of a course.
