The grammar section provides easily accessible information, with key grammatical points highlighted throughout, hundreds of examples of real German, and a full glossary of grammatical terminology. The verbs section offers 127 fully conjugated regular and irregular verbs. Major constructions and idiomatic phrases are given for all verb models. The handy vocabulary section covers 50 topics (such as family, free time, careers, computing, education, food and drink, health, and shopping).
This is a good book for a detailed crash course in German. It takes out the practice questions and readings that can clutter a textbook, and gives you just the information with examples. I like to refer to it when I'm beginning to learn something new (as a sort of launchpad) or need to refresh. Since German doesn't have its own equivalent of the French Bescherelle*, the verb charts are very useful.
*There does exist a German Bescherelle but the Bescherelle was designed for French and does not accommodate German verbs as effectively at the time of writing this.
A concise and no-nonsense approach to language learning. The first section can be read front to back, whereas the middle section is more for reference after a quick scan.
These verb tables been helping a lot the past two months. Also the vocabulary is a good way to build flash cards, with the verbs giving a lot of example sentences.
