This review is from: Cambridge Grammar for CAE and Proficiency with Answers and Audio CDs (2) (Cambridge Grammar for First Certificate, Ielts, Pet) (Paperback)
This book is excellent source of guidance to subtle grammar rules that may not be so apparent in everyday usage of the English language. lots of tasks to practice with answers at the back of the book. I would recommend it to anyone who has the will power to sit down and do some self-teaching.
