Title: The worst among my phuchases
Review: There are no explanations at all on the answers. The answers are only A.B.C.etc. They did not tell you "why". Besides, the CD sound quality is so bad, and you can not repeat the specific questions you want to listen. You have to repeat the whole section from the beginning, and it wasts my time.It can't even compare to Delta's Key to TOEFL(CD-ROM)(5*) and Barron's TOEFL 10th Edition(4*),
