This was the most frustrating review book I've ever used. The information appears to be concise, organized and complete, but the review questions and answers leave a lot to be desired. In one section, 10 questions were left unanswered. In several others, answers were there, but didn't match the questions (in numerical order). Many times the answer was written correctly but aligned with the wrong letter. The CD ROM was good, but several answers did not jive with information given in the book. All in all, this could have been a great review book if ANYone had bothered to proof read it before going to print. Very dissapointed, and I'd like a refund.
