I’m trying to read as much as I can and I’m almost halfway through the certification guide. It’s a good read so far and knowing that Narbik has checked the content means it’s good technical quality. It doesn’t go very deep into all areas because then the book would be 5000 pages instead of 1000 but it gives you a good feeling for what you need to study and I would imagine that this book would be essential for anyone going after the IE. When I’m done with this I’ll probably go with the Doyle books next.
