Have you already taken the class or are you doing the @home option?

I passed the GCFA back in the spring with a near perfect score, so I don't think the GCIA will be that difficult either as long as you've gone over the courseware. They don't ask anything except whats from the books. What I did to prepare is to simply review the books and make little tabs on areas that I thought was weak so I could find them quicker. Also you get 2 free practices tests after you signup in the SANS portal. After taking those you will have a good feel for the level of detail they are expecting and all the questions are multiple choice.

With as much as they charge, they better get you the practices tests. They help out immensely, as I saw my score go up alot after taking the first practice one.

Having passed both the GCIA and the GCIH I can honestly say that I found the GCIA more challenging due to the complexity of the content.  That being said I self-studied for the GCIA and used the SANS OnDemand method for my GCIH.

Going back and reading my posts on this thread, I had to laugh!  I accidently had this aimed at the GCIA, but in fact it was the GCIH that I was writing and meaning to ask about.  I ended up with a near perfect score on both exams and now on the advisory board for SANS.  It was a great feeling to do so well with a SANS cert like this.   

Thanks guys!
