SWELL OPEN is a service KTH offers all international students. It's a self-instructive practice course in elementary Swedish online.
SWELL OPEN uses the Bilda system, the KTH tool for flexible learning, and enables you to get familiar with the basics of the Swedish language and in some aspects also with the Swedish culture.
You can study the grammar parts and learn lots of Swedish vocabulary. You will also be able to do all the oral and written exercises and get to know Ville, the virtual language teacher.
