Cambridge - English Grammar in Use

There are 145 units in the book. Each unit concentrates on a particular point of grammar. Some problems (for example, the present perfect or the use of the) are covered in more than one unit. For a list of units, see the Contents at the beginning of the book. Each unit consists of two facing pages. On the left there are explanations and examples; on the right there are exercises. At the back of the book there is a Key for you to check your answers to the exercises (page 336).

There are also seven Appendices at the back of the book (pages 292–301). These include irregular verbs, summaries of verb forms, spelling and American English.

Finally, there is a detailed Index at the back of the book (page 373)
