Wiley CPA Exam Review 2012 arms test-takers with detailed outlines, study guidelines, and skill-building problems to help candidates identify, focus on, and master the specific topics that need the most work.
I prepared for the exam with Roger Philip CPA, which provides it's own study material but uses Wiley CPA for the study questions. So I can't speak for the study material itself, but the questions are very good and WILL prepare you for the exam.
Do all of them, and also make sure you get a version with access to download additional questions. This will allow you to focus in on areas you're weaker in.
Best prep material; however, it can be a bit dry. With the exception of a few up-dates, the questions remain the same from year to year. I have spotted a few typos in the multiple choice questions. It's helpful if you belong to a CPA prep forum or group where you can discuss such questions to clear up any confusion.
The Wiley books are the best study material for the CPA. I would highly recommend using them and forgoing the thousands of dollars you can spend on a review course. I've done both, and passed much more easily with just the books. If you're going to use them, focus on the questions more than just reading.
