For those looking for mock exams, here's the ones that I found very helpful. Make sure the test you are using references PMBOK 6. You should target 75-80%. Build up your testing stamina. You need to be able to do 60 questions without a break. Use a timer to track your completion rate. PrepCast - 120 questions Oliver Lehmann - 100 questions Edwel - 75 questions Agilemania - 150 questions TIA PMP Exam Simulator - These are the same folks behind the PMP Exam Simplified book mentioned above. Trusted Institute - Offers many long and short mock exams, including 180 count sets. BEWARE: There's a lot of PMBOK 7 here (like tailoring) and that is not on the 2021 version of the exam.
