Hello everyone,
I cleared the PMI-ACP exam this past weekend with 6 AT and 1 T. The following are the steps I used to prep.
1) Prepcast: I watched all the videos to for the 21 contact hours, more importantly these videos allowed me to get a big picture idea of what was being tested.
2) Mike Griffiths Exam Prep: I read this book twice. The first time I read it then did the end of chapter quizzes, the second time was a straight read through. This refined my understanding from the prepcast, it also reduced subjects/area to study. I.e the Prepcast discussed the Crystal method however since the book lightly brought this up, I didn't study the Crystal method at all.
3) Mike Griffiths' PMI-ACP workbook: I read this twice. The first time I read and did all the end of chapter activities and quizzes, the second time I read it and did just the quizzes. This is a FANTASTIC workbook, it only gives you the subjects that you need to study for the exam. I.e the workbook does not go through EVM, ROI, NPV, and IRR, these were not asked during the exam. The quizzes are also really well written, a lot more harder than the questions in the exam prep. This workbook ONLY goes through the subjects that you'll be tested on.
4) RMC Test questions: Great test questions, roughly 500 questions total. Most questions are short with one or two sentences, this will give you a really good idea of how the actually tests will be like. My avg was 78% through 500 questions.
5) PMTraining.com 1000 questions: Colossal waste of time. Most questions are repetitive and you wont be tested on it.
6) Exam Simulator: My four scores were 60%, 71%, 50%, and 60%. I found that these questions were harder than the actual exam. What I got most from these practices is how to dissect the question, quickly eliminate wrong answers, testing under pressure, and time managing. The explanation for the questions are also well written and really added to my understanding.
I hope these steps can help the next person pass their test. Good luck!
