Passed Security+ last night with a score of 850. I'd say that most of the questions were straightforward with a few obscure questions that threw me off.
I used Darril Gibson's book as my primary source of study and supplemented it with the CBT Nuggets video training series. There was actually one specific question that I found was covered only in the CBT videos and not in Darril's book, but most of the content was covered very well by Darril (thank you Mr. Gibson!).
