Reach your goal with clarity and structure!
The reason for developing this book:
I realized that the exercise books I have come across, in my over 20 years of teaching, are by far not enough to comprehend the usage of German grammar.
My excercises begin from scratch and slowly develop. I have elaborated these exercises in such way that step-by-step excercises lead you to a more active usage.
TrintCo GrammatikÜbungen is not part of the offer.
