Most accurate practice exams?

Sliznut

Just a quick question. I have the Security+ coming up by the end of the month. I think I have TOO many resources. I got the three book official CompTIA study pack and it seems fine. My question is that the practice exams on here and the ones in the book seem very different. I also downloaded a Pearson practice test on my Droid X and the questions on there are way more in depth. Any ideas what practice exams are closest to the actual exam?
