i have heard of several people that would just read through the books, set up small networks in their houses, and who got through the exam. One thing i recommend is a study partner. They will be able to ask you questions to quiz you, probe your mind for answers that they come up with, etc.

One piece of advice = set up a small, yet ISOLATED network. While studying for certs many people make silly mistakes, and end up having to reformat, etc., or end up having security issues. Don't put your main box up there, just buy a few 500 mhz machines and go at it.
