Hello, One of the nice and beneficial features of the DeutscheAkademie is the fact that it offers online course and exercises for free. Those are very beneficial when you want to learn more outside of class or just practice what you have already learned. I have very positive experience with online course and would recommend to everyone.I have no particular  topics or exercises that I like and I like to try various topics and see where I am at. It’s also nice that one can see results immediately and get a correct answer.The online course also has various topics and it’s a great helping tool. Thank you DeutschAkademie!
