Welcome! I feel your pain, as I am also a CTI grad...all the way back in 2010. What a wait it has been. Dispatch is a fun career! Just chiming in to offer some review advice in the way of materials where you could study on your own.
The first thing I recommend, and still periodically review myself is
"Everything Explained for the Professional Pilot" (This is a great resource for both pilots and dispatchers!)
http://www.amazon.com/Everything-Explained-Professional-Richie-Lengel/dp/0974261300
Also, another review resource that I would recommend is the
ASA Oral Exam Guide - Dispatcher -- which I think would be a good review as well (I also personally review this from time to time).

Anyways, good luck!
