I bought this book to accompany my learning German. It is very comprehensive but also very technical, I think it would be more suitable for people who study German in college for example. There are many grammatical terms in French which I have never heard despite my very good grammar "practice." I did not want to put myself in the French grammar theory in order to understand what we are talking in this book of German grammar ;-) To be honest, I do not understand 3/4 of the words used. I know, it is shame :-) I think selling it to buy a more accessible in my beginner level book.
