This book is for elementary (and lower intermediate) students who want extra practice in grammar. It covers most of the grammar areas in Essential Grammar in Use. You can use it without a teacher. There are 185 exercises in this new edition. Each exercise relates to a particular part of Essential Grammar in Use: Third Edition. You can find the Essential Grammar in Use unit numbers in the top right-hand corner of each page. You can use this book if you don't have Essential Grammar in Use because all the answers, with lots of alternatives, are given in the Key (pages 112-127). But if you want an explanation of the grammar points, you'll need to check in Essential Grammar in Use. The grammar points covered in this book are not in order of difficulty, so you can go straight to the parts where you need most practice. But where there are several exercises on one grammar point, you will find that the easier ones come first. So, it is a good idea to follow the exercise order in each section. Many of the exercises are in the form of letters, conversations or short articles. You can use these as models for writing or speaking practice.
