This CD is clearly a burn of a previously existing cassette. There is little control, from a CD point of view, of focussing in on content the way one might with a cassette player. Further, the English parallels that appear in the companion book are missing. Without the book the usefulness of this CD is limited. In fact, DON'T buy this one by itself. The lack of reference to English meanings will make you crazy. The characterization in the dialogs is very spotty quality. The organization is not very good. If you have the book it will work as a complement, however limited. In the price range, with the book to put things in perspective, it is still a reasonable deal if one needs something right now. Better advice: wait for the 2006 version which one sincerely hopes will overcome the problems with this edition.
