YOU MUST BUY THE AUDIO-CASSETTES,
This review is from: Delta's Key to the TOEFL Test (Book and CD-Rom Edition) (Paperback)
The book is very well-organized and offers a lot of practice. It is probably one of the best textbooks for TOEFL preparation.
It could have been rated 5-STARS but I rated it only 3-STARS because it should be clearly said that the AUDIO-CASSETTES are fundamental for the listening preparation and that the CD-ROM doesn't contain the same listening material. I bought the CD-ROM package and I have not audio material for the paper-based test.
