I was caught off guard when I encountered endless lengthy questions on the PMP exam. With the exception of 5 questions (that I can remember), all of the exam questions were extremely lengthy! I didn't have enough time to answer all of the questions. I completed all of the mock practice tests I took with in 2.5 or 3 hours and I was scoring in the 80's, but nothing prepared me for what I experienced during the actual exam! I think only a speed reader could have finished the test in time. I used Andy Crowe's study material in addition to Head First PMP and the PMBOK.
