First off I know it's not the newest exam content, but I think it can help you understand concepts still covered quite well - especially if you still feel shaky on something from another training method. If nothing else the practice labs are of value. Hope you all enjoy this one!

Includes the following modules:
CompTIA Security+ 2008 Express Guide
CompTIA Security+ 2008 Practice Lab I
CompTIA Security+ 2008 Practice Lab II
CompTIA Security+ 2008 Practice Lab III
