This book is a practice of German grammar, nothing more nothing less. Between its bright yellow pages there lies a brief explaination of practically every German grammar rule of any practical importance, with exceptions of rules being highlighted.
This brief explaination is followed by a page of practice sentences which illustrate clearly the point of grammar being explained. This makes it invaluable not just for students learning german, but especially for people living in Germany an looking for examples of how a rule can be applied to everyday speech..
I spent one year as a student in North Germany, and after discovering this book after about two months, I would not go to Germany again without it.
