"I teach German to some asylum seekers from illiterates - also in their mother tongue - to teachers and entrepreneurs without being a German teacher myself.

The practical instructions on Dative and Accusative case have helped both me and the students. I guess the state teaching must not be top notch.

So they learned from me for the first time that certain prepositions require a certain case. With your help, I practiced using these two cases with a teacher from Afghanistan for four afternoons and I think she is fit for her A2 and B1 exam.

I especially liked the summary of div. prepositions for dative, accusative and their overlap."

"This is the first time I really understand German grammar thanks to you. All your explanations are clear and very well structured. You have made my learning and consequently my life easier."

"Hello, dear Jan Richter, I have been in Germany for years. I have all your Ebooks and must say that many knots have burst with me . I would like to thank you. I find your weekly courses very good. Although I have your Ebooks, however the courses push one forward and one learns even more! Thanks again!"
