Good morning, James, and sorry for the delay,
The PMP exam has substantially evolved since when I took it in 2019. I have heard that it is very Agile/iterative focused now as opposed to traditional "waterfall" project management. The PrepCast Exam Simulator has also evolved to line up with the test. With that, you should probably get very familiar with Agile style project management more quickly than I did.
I used the simulator not as test of how well or poorly I did, but to identify weak areas of knowledge and understanding before I sat for my exam.
Hope that helps!
Harry
