To enrol in a course, you first have to register as a user on the European Schoolnet Academy platform. In order to do so, please visit the registration page, where you will be asked to provide your details.
Once you have created your user account on the European Schoolnet Academy platform, you can enrol in any available course by visiting the course's homepage and clicking on the blue "Enrol Now" button just below the course title.
You can enrol in a course at any time after registrations have opened. You can even enrol after the course has ended, since all the materials will remain available for perusal. The difference is that the course will no longer be moderated, and you will no longer be able to earn the badges or the certificate.
