The answer to your first question is that we will be updating our exam results report to be consistent with what PMI is using: Needs Improvement, Below Target, Target, Above Target. This will be implemented in the next 2 weeks.
You asked a second question: " Are there any past exam questions provided to test takers by PMI (not the three listed on their website) with examiners review? PMI's exam analysis result is not detailed and unhelpful for individuals interested in retaking the exam."
To my knowledge, I am not aware that PMI makes any specific or sample exam questions to those wishing to take the PMP Exam.
I wasn't aware that there are three sample questions that PMI provides to members, where are these located?
I know this is something that is very frustrating and limits your ability to know why you didn't pass and prepare better for your next attempt.
I hope this response helped you.
