I just passed the PMP above target in all areas and the PM Prepcast was a big help in my four-month preparation, in addition to a few other materials. The most helpful thing to me was the practice exams and mini exams. I probably took 10 mini exams and 2 actual (but never had time to do the whole test). There was a lot of Agile on the test, felt like more than half to me, and my Agile knowledge definitely came in very useful.
