AR's 35 hr./one month prep. course, keeping up with the work and studying each week to build upon it so I could retain the information, along with his mindset teaching helped me the most. I am not good at taking standardized tests so the mindset and finding "key words" in practice questions helped me the most to identify right answers. I also used PMI mini exams and took one full mock exam on PMI. For the full mock exam, I reviewed all my wrong answers, made sure I understood why, and uploaded my results into ChatGPT, prompting it to provide a summary on Process, People and Business, to identify where I needed to review more.
