Yes I have. I got the material because the bastards cancelled my class due to lack of sign ups. It is 400 bucks and very very comprehensive. You get 4 different books. One is a classroom workbook which you are supposed to use during lecture. I will probably skip the class since it costs an extra 500 bucks. The material is very well written, although there are quite a few mistakes in the questions and answers. Classroom workbook asks a lot of theory type questions, which can be good to give you different way of thinking about the material. You also have other books which are kind of like the kaplan blue book, and summarize all the material. They are much more comprehensive than kaplan though. You have another book which is filled with questions divided by material topic. And you get the four exams and answer sheets which you would normally take on a saturday in class. If you are disciplined, you will probably get more done with the time you save not driving to class. As far as difficulty level, I would say the questions are similar, if not harder than destroyer. Call their office in Westwood, and you can place an order. I'm in LA, and got the stuff in one day.
