Additional online subscription required before this book can be used
on 2 March 2015
Useless on it's own without buying an online subscription to companion study material. The latter accounts for about 50-60% of the Student's Book's content, so the book itself is limited to the point of being almost worthless as a comprehensive study tool unless this extra subscription is paid for. This was in no way made clear in the marketing material for the book.
