Is there any materials out there recommended for visual learners to study for the CGRC? I've been going through the NIST pubs, and although they are full of great information to reference, I can't bring myself to go through them as the primary way to study for the exam. It would be nice if there was a good study guide that summarizes a lot of things that I need to know for the exam. I've seen a good study guide for the CISSP, but not a whole lot out there for the CGRC.
