Hi. Let me share more about my experience of the exam since some of you may have interest and have similar experience with me.
Sarah: I think the actual exam questions are similar to those of the PM Prepcast exam simulator, short questions are expected. It's always a challenge for me to keep focusing on the questions for 4 hours. I didn't have much time left, just 15 mins spared before the exam ended.
One of the tips after doing the practice exams is that after the planning stage, if the project have something wrong (scope change, schedule change, stakeholder change, etc) , the action should be taken is always to log down to issue log and go to ICC. It always help me to make quicker decision during exam and not to be trick with other choices.

Also, I trained myself to read through all the answers and cross out 2 obvious wrong answers by using right click of mouse, then I can have a better guess from the remaining 2.
Hope it helps and good luck for the ones who take the exam.
Isaac.
