Under myPMI go to your dashboard. Once you are in your dashboard go to e learning and it should be there. Good luck, I found using the PMI practice exam to get use to how the questions are formatted and it's ambiguity really helpful. Don't get discouraged by it, use it as practice
I finally figured out how to get in yesterday and took it. It is nothing like comparing it to the PM Precast exam simulator...I stopped and cancelled out after 100 questions.
I cannot remember how to get into it as I struggled as well to find it. My opinon is to find an alternative free exam simulator.
