Edit 7/2/2014: I passed and this was my sole source of study material, so I'd say it was pretty good.
Without an intimate knowledge of all the test questions, it's difficult to know how accurate and thorough books like these are. I read all the pages and am working through the 8 practice tests on the included CD and take the tests next week. Even though I feel like I should wait until after the test to rate it, but I guess it was good enough. ⁀⊙﹏☉⁀
