Hi guys!
So I've finally passed my GCIH. Took the class in March, and the exam in May.
1st Practice exam: 89%
2nd Practice exam: 86%
Actual exam: 92%
Like everyone else has said on this forum, the index is your key. It helped me confirmed my answers for at least 70-80 questions.
My index was simple and about 40 pages long:
Topic, Book no., Page no., Description of the topic.
My advice is to read the books while indexing, and listen to the given audio files while commuting. John Strand was pretty entertaining with his experiences and he definitely impacted the way I conduct my security awareness talks 

I'm thinking of the FOR500, FOR508 or SEC560 next, depending on the way the wind blows in the office. I may have the option for moving into web/network pentesting, but blue team work is more natural to me.
In the meantime though, I'll be lurking on the other subforums while I work on elearnsecurity's threat hunting course, or maybe the CISSP
