I passed my PMP on 29th Aug. My experience is the questions are not tough at all. You need to be thorough with the knowledge areas and process groups. It tests how much can you apply the various tools and techniques. But then i have seen many PMP aspirants and passed candidates speaking about brain dump. Well to be honest i too had plans but when I sat on the chair in front of the computer I realized that its not needed. I guess having ITTO in front of you is absolutely not needed. If you have understood the flow you can easily answer all input/output questions.
