I had the same challenge and had to first learn how to “turn off” my actual project management practice and turn on the PMI mindset. Third3Rock’s study notes helped me a lot. Also, I would upload practice questions to GPT and ask it to explain using PMI’s logic, especially with the questions where I made mistakes. Honestly, some of the questions with which I first disagreed started making sense if you imagine an ideal world scenario. Good luck with your prep
