I recently took a PMP prep class and felt good about the material.  I did 100s of exam questions and thought I had a good handle on things.  Then the PMP Exam came and I did horribly.  What can I do to answer the situational questions better?  Is there a training site that helps disect the questions better?  Just reading the PMBOK and other books just doesn't cut it.  I see many people pass with 4 or 5 proficiencies, and I am very skeptical about that.  Any advice from others?

Thanks
Ben
