The course licenses are valid indefinitely until a course has been started, after which you get 30 days to complete the course.
When buying a course from our webshop we want you to be able to plan ahead and buy courses needed in the future, perhaps taking advantage of a special promotion, getting a lower price on the courses you know you will need later on.
Therefore the course licences you buy are valid indefinitely, until the end of times...so you don't have to worry about them expiring.
When you have started a course you will get 30 days to complete it. Of course if for some reason you didn't manage to complete it in time you can always contact our support team (support@scandlearn.com) to extend the period.
