We recommend to have at least basic knowledge of the language in the host country before starting your studies. You can start learning the language in Berlin- these are possible options:
· Language Center of the FU: http://www.sprachenzentrum.fu-berlin.de/
· Language tandem of the International Club of the FU: http://www.internationalerclub.de/
· Adult Education centers: http://www.berlin.de/vhs/kurse/sprachen/
· Language and Culture Exchange of the TU: http://www.skb.tu-berlin.de/
Many host universities also offer language courses before the semester starts. Please contact the Erasmus coordinator at the host university for more information.
