Since everyone else is posting about passing this one, I figure I better jump in to.

Passed today with an 850.
This was my first CompTIA exam and I have to say - good god they need to fire whoever does their quality control! Out of 100 questions I had 5 on the
exact same piece of technology. 3 of the questions were essentially the same question posed 3 different ways. Combine that with the fact that the exam was riddled with grammatical, spelling and poorly worded questions/answers and it gave me a really bad overall impression of the CompTIA exam development process.
As for the resources I used, I decided to try something a little different and have a go with some "audio learning" on my iPod so I bought the PrepLogic Lecture Series for the Security+ exam, and while the audio itself was clear and the trainer did his job it didn't even come close to the depth required to be able to pass this exam. For someone new to IT using only that as their resource and based on the questions I got, a score of 300 something wouldn't be unrealistic. On its own it just doesn't cut it, not even close.
Knowing I needed something else, I picked up the Syngress Security+ book based on the recommendation of some of you guys here, and its the opposite - "comprehensive" is an understatement.

I couldn't bring myself to read past the first chapter since it was soooo much review and I just wanted a recap to refresh my mind on the things I don't work with and some of the terminology. That's when I found the "Fast Track" PowerPoint slides on the CD - thank you to the author for including that. I flipped through the notes on those slides and read in depth about anything I didn't understand.
Ran through the different Transcender practice exams a couple times on Monday/Tuesday night which helped me to focus on the bits I still didn't get.
So final score:
PrepLogic Security+ Lecture Series
Syngress Security+ Study Guide
Transcender Security+ Practice Exam
