Just got home from passing my Security+ test! Scored a 775! I used a myriad of resources, including Exam Cram, some of Darril Gibson's book, and some of the tech notes from this website. Thankfully I checked the forums before taking the test and I was able to mentally prepare myself for the simulation questions, which are actually pretty easy. Thanks to this site for being a wonderful resource in exam prep!
