I am writing this testimony because the PMP Exam Prepcast website was a large reason why I passed the PMP. 10 straight months of studying prior to purchasing these tests. The nine tests that you can purchase were a life saver. I studied all the material, PMBOK 5th Edition, several other books and increased my knowledge base with every component to the PMP and all the ITTOs. I used the nine tests to gauge where I was at. The way the results laid out the scores is what helped me focus my additional studies. I honestly thought that the test was going to be more difficult than the questions on the nine exams but that was not the case. This of course is my opinion. I would definitely recommend PM PrepCast to assist you in your studies. Mahalo PM PrepCast and thank you for your support.
