I didn't use the Rita book for prepping for the class. I used the PM BOK, APG, and Simulator 2021. I read the APG twice and read sections separately when I needed to understand a concept better. I read the PM BOK once, almost but I read sections in PM BOK a lot. I used the PM Prepcast 2021 simulator for prepping for the exam. You need to understand the concepts of the processes but not to the ITTO level. For the last 4 weeks (2-30 Mar) I only used the PM Prepcast simulator 2021 and used the PM BOK and APG for reference. I did all 4 exams. Then I went through each exam for several days to understand why answers were wrong and why correct answers were right. I did that for each of exams. Then I started again to go over each exam question. I got to re-do 2 exams twice before it was time for my exam. Bear in mind I am not memorizing anything. In fact I couldn't remember the any formulas when I went in the exam. Basically I was willing to take the hit for not knowing formulas because I felt I would have more concept questions than formula questions. After you do the exams back to back, you will begin to see how questions relate. When I say relate I mean conceptually relate. When I was going through the exams the second time (I only was able to cover 2 for a second round) I covered the answers on the screen by holding a paper in front. Then I answered the question by giving the conceptual answer. I did not memorize any questions. That would be hard because there are 180 X4 . Then after explaining to myself what was the correct answer I would uncover the choices and explain to myself why the other 3 answers were wrong. If I didn't know why an answer was wrong I'd uncover the explanation and go over why and answer was wrong. Remember I am answering the questions conceptually; not an exact answer so my "conceptual" answer was more in depth than a single word answer. This exam you have to understand concepts. They really didn't have any questions that were just definitions. Even the matching. That was a scenario. There were several questions that you have to relate your real life. I don't think the answer would be in a book. Of course I don't know what I answered right or wrong so I don't know if I got those right or not. All through out the exam I thought for sure I failed. When I did the second third I still thought I failed. By the last third I figure I had nothing to lose. I was s shocked that I passed. That's why I think we all know more than you think you know. These last few weeks I recommend do the 4 mock exams. Don't go through through them too quickly when you review each question. Understand the concept. Read the explanation that PM Prepcast gives you. Don't think about pass or fail when you're in the exam. Focus on the questions. Put yourself in the scenario. After the first third, I started to think about how I was going to tell my boss I failed and how would I tell my friends. That distracted me. So don't think about anything other than the question you are answering at the time. Stay focused. I'm sure you'll pass.
