I took the security+ exam last Thursday and passed with a 814 score. I had scheduled my CISSP about 3 weeks ago before I knew I was gonna also do the security+. Anyhow, I took the CISSP exam this morning after pulling an all nighter for additional studying and failed! Got a 645......I was basically delirious in exam room from lack of sleep! The lesson I learned here is that I actually have to study and be true to it instead of taking breaks in between studying...likes I took a couple of days off. I have a serious condition of short term memory so I can't study for a month and then take the exam....I've always had the memory blur! Hope to take this test in 30 days!! $600 is just insane!
