Query: Decent study guide

I found the Sybex book to be full of all the information I need to study for the Linux+ exam. It is rather a dry read though, but it still takes time to explain things in simple concepts. I enjoy the fact that the practice exams will work in a linux environment, but I was a bit let down when the pdf version of the book would not work in FedoraCore 4 due to some security measure on the pdf. Overall this is a decent book for the price.
