I bought this because I enjoyed the main 中級から学ぶ text, and figured this would be a good supplement, and it is, but... by the third page, it instructed me to listen to the cd, which doesn't come with the book. It's sold separately for \7,300, more than 3 times the cost of this book. So, I can't do a large percent of the text properly, and one third of the book is simply the script to the cd it doesn't have. I've bought lots of books that come with a cd for \2500 or so, so a package that costs near \10,000 doesn't feel that great.
I actually feel a bit ripped off. A text should come with the cd.
