To state that the GARP books are not adequate to pass the exam is absurd - people really need to reassess their level of commitment to this designation if they are claiming the exam is unfair or too difficult. If you want to quit because it is too difficult, then quit. The rest of us will continue working hard to achieve the worthy goal of earning the designation.
I think you are too harsh.. aren't people writing in this thread to express their feedback? not to receive a harsh judgement instead? Isn't that the purpose of this thread? You do not even write any single feedback in your comment. Maybe you are too smart for most of the people in the world, maybe you have very good experience in everything you have done in finance.. but please consider, some of these posts maybe came from university students who still taking uncertainty in exam results into frustration.
