Practice Grammar for Intermediate Level, a concise version by Friedrich Clamer, Helmut Röller, and Winfried Welter. Teaching and practice book, 96 pages, Level C1.

In terms of structure, organization, and presentation, the intermediate grammar successfully continues the work of the basic grammar. The rules are placed directly before the exercises, allowing solutions to be written directly in the book. Special emphasis has been placed on learning lists for the governing of the most important word classes. Some lists include frequently used entries from the basic level, but they have been included due to their fundamental importance for learners. Additionally, it cannot be assumed that all learners have acquired the basic knowledge after studying the basic grammar. Therefore, repetitions are essential to create a comparable starting point for everyone.
