I'm in need of a little help from you all. It's been awhile since I have posted on here, but I still lurk multiple times each and every day. Since I last posted I got a new position in my company and they have paid for my SANS/GIAC GCWN Course and Exam.
It expires at the end of August (unless I pay for an extension).
My question(s) to you all who have taken a GIAC exam is how did you finalize your preparation for the exam? I know its open book and I have been reading that I should prepare my own set of indexes to bring into the exam. This seems to be where I am stuck though. I have never taken an open book exam before, so I am kind of at a loss for how to properly index 5 books efficiently.
I am re-listening to the videos and going back through books, but each time I try to setup an index in Excel, it just doesn't make sense. I know Excel very well, I just dont seem to be able to index at all.

Any help and tips you all could provide would be great as I am very nervous for this exam and when it comes to exam-taking, I am not the best (I do better at sims)
Thanks,
BreadFan
