Query: Great book, Well Written, and Error Free

I was a hoping I didn't need to read this big book to pass the test. But things were explained well and it was easy to understand. I actually enjoyed reading the whole thing. This book turned out to be one of the best computer books I've read and the best one on a cert. I haven't liked too many certification books, they seem shallow. This one had depth and a lot of good hands on tips. You can tell the writers have been out in the field. Buy it for the info. When you're done with the test this is the book to use on the job. Thumbs up!
