Query: A LOT of information, but also a LOT of confusion!

I bought this book hoping that it would give me a place to START my CCIE studies. However, because of the way the book is set up (sections, paragraphs, grouping similar concepts) it was so counter-intuitive that I couldn't graph a lot of the concepts. I just plain couldn't tell whether I was into a new subject or still in the old one! Still, there is a LOT of good information in here, and I found gems of wisdom in some of the subjects that I already knew. I recommend this book to established pros, but rookies stay away!
