I passed PMP exam on 1.02.2011 (PMP No 1387872).According to me the only way to pass PMP exam is to read PMBOK as many time as possible & make notes of the important points from the PMBOK.Initially i started reading Rita Mulchay book but i found the content & the questions very absurd, then i concentrated only on PMBOK & cleared the exam.Remember what matters is passing the exam & not how much we score in the exam, Minimum passing or 100% score is all same.
