I'm surprised no one else has posted anything about this yet...
I bought this book as I saw several people had mentioned it was a good read before the CEH exam. I have read through it and taken my notes already, so I decided to take the written test in the back (110 questions). As I was comparing my answers to the answers in the back, I noticed several that just didn't make sense to me as to how I could have gotten them wrong. Upon further inspection, I noticed that some of the letters in the back, did not correspond with their correct letters in the question. The text explanation and answers all seem fine, just some letter mix-ups. It's a little confusing when you're just comparing letter-to-letter. Here are the fixes:
A. 27: D should be C
A. 31: B should be D
A. 40: B should be C
A. 51: B should be A
I suppose it's a good sign of preparedness that I can recognize when my answers should be correct, right??

Hope this helps someone
