The Big Book of English Exercises for Beginners 

The Big Book of English Exercises for Beginners is jam-packed from cover to cover with a great selection of entry level exercises and examples. This book provides teachers with a really useful material of no-nonsense grammar exercises that they can dip into and use in class with students. 
It is also ideal for students to work with at home and learn English on their own, since the exercises have a intuitive structure and the answers are all printed at the back.
The book is divided into chapters and is graded in difficulty, so that it begins with some basic stuff and builds up to more challenging grammar activities.
