IELTS Writing 9.0 Proficiency © Task 1. IELTS Academic + IELTS General Writing Task 1. Includes IELTS Writing Samples for IELTS Academic Training & IELTS General Training (IELTS Vocabulary Book)

I bought this book, but in the kindle version of this book, the content turned out to be totally another book - "101 Grammar Rules for IELTS".

Definitely helps. Some mistakes are so commonly used that when I speak correct I feel I'm wrong & I doubt myself. I m glad to have come across this.
