It really give you the important grammar skill for IELTS test, and also it's a general grammar reference. I used this book and I get 7 band score in my Ielts exam!!!! The book is easy to study and there are a lot of practice to do and also a lot of listening exercises!
This excellent book fills a long-standing, crucial gap in the learning materials available to IELTS students and instructors, and is currently the only book which specifically helps IELTS students in this area. Although the IELTS test doesn't contain a specific grammar module, recognition and appropriate use of grammar is undeniably important for success in the other skills modules. All grammar points needed for IELTS are covered in the book and presented in context through listening (provided on the CD) and self-discovery activities. These activities are especially useful in helping students to learn and remember new grammar. Each unit also provides a rich variety of examples to illustrate the grammar point, as well as clear explanations on usage. In addition, there is a wide range of interesting and motivating practice tasks from the IELTS reading, writing and listening papers, which provide students with plenty of opportunities to develop their skills. This book fully deserves the 5* rating and I highly recommend it to all IELTS students and instructors.
