I passed the PMP exam on my first try on May 29. I owe much of my success to the PM PrepCast exam simulator. It really got me prepared for the actual test day. I knew what kind of questions I might see and I wasn't nervous at all. In addition to using PrepCast to get ready, I also used the Rita Mulcahy 10th edition PMP Exam guide, I read the Agile Practice Guide and I also used Joseph Philips PMP Exam prep course on Udemy.
Oh, and I watched Ricardo Vargas's YouTube video on the processes.
Thankfully, there are a lot of really great resources out there to use to help you prepare and get ready for the test.
