I have cleared my PMP exam on 1st September 2009 in my first attempt.
Thanks to Mr. Cornelius Fitchner, the quality and diction of prepcast is of high quality. Tips provided for answering the questions are excellent. These tips helped me a lot in making intelligent choices for all the questions where I was bit doubtful.
My Recommendation to all aspirants, that listen the tips and detailing of concepts carefully, tips and illustrations on scenarios are very helpful while answering applied questions.
I experienced that while making intelligent choices, Mr. Fitchner's voice was echoing in my ears

. So for any aspirant just hear prepcast repeatedly and than attempt the exam questions chances are the there you will find that when you will attempt the questions, you will find Mr. Fitchner's voice echoing in your ears and helping you to make intelligent choice.
good luck!
