I just took the exam for the second time; scored a 645. I failed it again. The first time (August 200

I scored a 615. I used the Exam Force materials and several text books. I am not saying the materials did not help. I have been in IT since 1999. I have been a network admin since 2003. I know access control and certificates tripped me up. But there were questions the study materials did not cover. :-0 I normally don't attempt cert exams after failing twice. I missed MS Access 2003 twice. Never bother with it again. However, I want to get this one under my belt. I am considering taking a the Security+ class at Microtrain. After six months of self study, maybe there are some concepts I just can't get one my own.
I appreciate any comments.
