The interactive online course "Harry – gefangen in der Zeit" will unfortunately no longer be available starting January 1, 2021. This is due to the fact that Adobe Flash is ending its technical support. But the animated radio play and the accompanying materials will still be available.
If you are looking for an interactive German course, you can try "Nicos Weg" instead. In this course, beginners from level A1 onwards can make rapid progress. Learners just need a smartphone or PC to reach their goals with "Nicos Weg."
