I actually use Wiley Books, Question Bank and Wiley Focus Notes, predominantly. I understand Yaeger uses the materials as well. I would recommend, for all sections, to read all the materials, highlight it, take notes in the margin, and re-read it all and take notes on a legal pad. Thorough notes. Then, take all the MC questions and SIM questions at the end of each chapter. After completing them once, do it again. As you are doing the practice problems, always keep in mind why you are getting answers right, and why you are getting them wrong. Read the wrong answers anyway. The wrong answers sometimes contain a lot of knowledge. After that, review notes from your legal pad and Wiley Focus Notes, and keep practicing problems over and over again from the Question Bank as well as from the back of each chapter of the book as well. I think the key is always having a good grasp of the “big picture”, then building on all the detail and minutae from there. And the repetition of doing practice questions and practice exams over and over again will build further fortification of the materials. Remember: the key is when you do all the practice questions to know what's going on, to really understand the wrong and the right answers. Don't kid yourself by memorizing answers or blowing by things that you feel you may know. Once you have practiced a lot of problems and review the notes simultaneously, you should have a good grasp of the materials. And if that's the case, you will do well on the exams. The exams are fair compared to the study materials, in my opinion. It's a challege, but it's a realistic and acceptable challenge. The only thing really tricky can be the SIMS on the real exam, but the more you truly understand the content of the materials, the better your chances of passing in any event.
I think for me, Wiley is good enough. But to fortify, you can use a Becker or something for a certain section or two that you find difficult. Or use it for the whole CPA program. Whatever you wish. Best of luck!
