CISSP since 2005
It took me two tries...Flunked the first try by one question. Looking back I feel I didn't properly fight the test to the bitter end. I finished in under 2 hours.
Try #2 was no picnic either. I took 3.75 hrs, because I re-examined each question/answer. Against my usual advise I changed 4-5 answers because I saw provable mistakes.
I read the BOK, and used ISCs new test question book.
Study hard...stay in the fight, you'll do fine!
