Passed PMP exam yesterday in 1st attempt. The Prepcast exam simulator helped a ton for the exam, don't think would have passed without that. I when through the Joseph Phillips course and the PMBOK guide as preparation for the exam. The Joseph Phillips course though good to study , does not have tests that can simulate the variety and difficulty of PMP exam. Glad I subscribed to the Prepcast exam simulator and went through the timed quizzes and exams. The timed quizzes were perfect in the sense you would select the no of questions and thereby tailor them to your schedule. Also went through the explanations for what I got wrong and also correct for the questions. That helped a lot. All of the answer explanations have the corresponding PMBOK page number which is useful to check out. Also viewed Ricardo Vargas and Aileen YouTube video's. The PMP exam i would say was moderately difficult and I had to use almost the full 4 hours. Glad to have got the congratulations message at end of it !
