As an Aupair in Germany you should improve your german knowledge.
Usually you will learn german at the "VHS" = "Volkshochschule", the most popular institute in Germany.
The usual german course is about two or three times per week, generally at afternoon or evening time. Each course day you will do have two german lessons.
This usal german course for Au-Pairs will be paied completely by the Au-Pair family.
Sometimes you might heard from your friends that they went as an Au-Pair to Germany and they did attend an intensive course.
Sometimes you will do have this posibility. All of our Au-Pair families will fill in a form about the posibilities for the Aupair to study german. You will get the information when you receive the other documents of your Au-Pair family.
Please consider that it depends not only of the time table of the Aupair family if you will attend german intensive clases, but also of your economic posibilities. Intensive courses are very expensive!
