Query: It's a Guide not a Wizard

Excellent guide, but you'll need the classroom course and hours of studying...It's not a wizard like some people think, you have to analyse because the exam uses cases and several questions about each case, it's not just memorize steps and if you are preparing for the CCNA too, it is better.The CdRom include a simulation test...believe it or not, I found some equal questions in the exam. I passed because I had patience to read and understood each case in the exam even I don't speak english.
