So its down to the wire. Only 2 weeks until I take the exam for the first time. I just recieved my course material for my official ISC2 course, and this is what they sent me. The "Official ISC2 Guide to the CISSP CBK (Second Edition)" from ISC2 press. Up until now, I've been working with all Shon Harris material. Her all-in-one guide, her practice tests book, and her audio lectures. But now that I've started looking over this official ISC2 guide, I'm wondering if Shon Harris is serious overkill. Either one of two things is true here. Either the official ISC2 book does not adequately prepare you for the exam (this seems unlikely to me) or the Shon Harris All-In-One book covers WAY WAY WAY more material than is necessary. So two questions for those that have taken the test...
Is Shon Harris' all-in-one guide overkill?
Does this Official ISC2 Guide adequately prepare you for the exam?
