Proudly allowed to call myself a PMP now. I succeeded at the exam on the first attempt, but my advise is not to underestimate the required preparation. Through my preparation I have seen a lot of emphasis on the formulas. You do have to know them, but the PMP isn't a math exam. For me, the "situational" questions are key. On the exam day, take your time to read and understand the questions. Preparation exams are of good help for this. Finally, key trick for me was stress management. Everything surrounding the day of the exam is quite stressful, and the time limit add up to this stress. Everyone has his own way of dealing with stress, but be sure you address it.
