To ace the test, you should go through their whole compendium. I know that's not practical for a lot of folks, but if you take it seriously it is akin to an associates degree in Arb. I studied off the guide and passed, but I would have killed it if I'd gone through the CEU stuff first.
(PS, sorry I've been away for so long. Plowing snow all winter and not a tree job to be found.)
