Apart from that, foreign languages are also increasingly sought after by employers. There are many ways to learn German prior to your stay or while out there. Whether you learn the traditional way by joining a class, or whether you team up with a German language tandem partner or flatmate, learning German can be great fun and hugely beneficial.
A good grasp of the German language will help settling down in Germany. If your course is in German, you need to know the language well enough to follow a lecture or seminar discussion. Many courses in Germany are offered in English. But even if you decide on one of them, you still need German for daily life.
