I've come across an interesting series of blogs by Wendel Odum on Network World that discusses preping and sitting the CCNA test by the man himself.

I am presuming, as it's Wendel, he has already cleared the NDA with Cisco before the blog went public on 11th September or it would have been pulled by now.
