Query: Inconsistent throughout

I read this book cover to cover and pass the exam. BUT not because of this terrible book. I had a TestOut CD-Rom...The wording of the author is strange and inconsistent. The CD-ROM were terrible horrendous. The author only appeared (in audio) in few example and the rest was a woman's voice. This woman doesn't know anything about computer period. This is most evident in her inappropriate pause of her speech. My advice to you the shopper DO NOT buy this book.
