A Duales Studium is not a vocational training (Ausbildung) in general. There are some university of applied science (Fachhochschule) with a combination of university courses in Duales Studium and with a vocational training (Ausbildungintegrierte) together: but the courses are selten and it is difficult to get a place. If you need an Ausbildung-Place for the Ausbildungsduldung apply for a Ausbildung. If you are in Belrin you can get a fee consultation by the LernLaden Neukölln, otherwise have a **** for Bildungsberatung in your city of residene.
