I've purchased this book (second volume as well) in order to do more practice in addition to my uni materials. I still have some way to go until I'll be able to use the book, but I can tell that it's a great book, even if you don't plan on actually having the exam (you can simply test your level and get an overall idea of how the exam is) . It basically contains an exam sample, and it's structured exactly like a booklet. It has answer sheets, audio CD for the listening segment and answers at the end to check how you did. At the end there is also a section that seems to explain more about the exam and possibly even how it's graded.
Delivery was fast and the price is great comparing to other suppliers (on Amazon it's double the price).
Overall, it's a great book, totally recommend!
