I've used the materials for AUD and FAR. I passed the first time both tries. I skipped over about 75 pages in FAR because I knew that the stuff was not going to be on the test, but I felt it has been good.
The basics:
-It is a self-study program with no set program of how much you should be studying each day, it does have a recommendation but it is ridiculous and not worth looking at
-Books with software that has only multiple choice and simulations
-No IFRS – not sure what they will be doing for 2012, but this is the biggest weakness
-The support staff is extremely amateur
-It is very cheap (relatively), I got all 4 parts with software for $700
-The software has been buggy for me where one week it would freeze every 50 questions or so, it's off and on
If you need a lecture or have a hard time studying on your own it is not for you.
