"em Ubungsgrammatik" is a very user-friendly grammar book. Each topic is presented as a double-page spread: the left-hand page introduces and explains the grammar structures and rules to be studied; the right-hand page is the practice page with a range of exercises based on authentic material in the form of newspaper articles or dialogues. This format splits grammar into manageable portions covering enough material for one lesson and making it easy for students to concentrate on the point in hand. All the rules are clearly explained from the learner's point of view with special attention given to areas that frequently cause problems. The answer key is integrated into the grammar itself. Since no grammatical knowledge is required to understand the explanations, and the answer key is included, "em Ubungsgrammatik" is ideal for self-study and class use.
