important notice

Dear participants,

Due to the current situation and the further spread of the coronavirus, we unfortunately are forced to temporarily close our German language training centers. This closure is provisionally valid until 19.04.2020.

We hope that the situation will quickly return to normal and that we can soon resume our usual operations.

Please contact our customer service if you have any further questions:
