All our studies are taught in German and for the program itself, you will need a language skill certificate at the level C1. The language requirements for admission are A2. So, you can admit to the study program as a non-degree student and take language courses within the training course „Vorstudienlehrgang der Wiener Universitäten“ (VWU). As soon as you reached C1, you can sign up as an ordinary student.
