Man, I thought the CWSP was bad... This exam is way too broad to cover the objectives in the detail it does.
I used the Wiley, Sybex, and Exam Prep books for my CEH-specific resources, and I added Hacking Exposed (sixth), Pen Testers Open Source Toolkit, Gray Hat Hacking, OSCP course materials, and various others, and I was still coming across things I hadn't even heard of. I can't go into detail, but I'm failing to find any mention of a couple of tools in their course outline (which is already enormous) that I received multiple questions on. The rest of the exam was all over the place. You'll be asked for a basic definition of a Security+ term one moment, and then you'll be required to analyze c/perl/shell code the next. I thought about half the questions were well done, and the other half made me swear at my computer (I was fortunately the only one in the room).
I managed an 84% overall, and I took about two of the four hours allowed. Self-studying for this one would be a ***** without experience and a lot of solid knowledge in many different areas.
I'm going to try to wrap up the Offensive Security OSCP and OWSP by the end of the year. I've already gone through the materials once; I just need to work on the exercises again and take the challenges.
