I did my ccac exam about 2 years ago and its tough one. Its been my experience to just read the book and study it completely (Mines loaned out), The question bank is huge (2000 possible questions). If you can get ahold of the little blue caac exam book it would be better.
If your in China now I can hook you up with a guy that can get you one (borrow his).
PM me and let me know.
