TOPIC: Difficulty of real vs practice exam?

Hello everyone. I came across a forum post where someone mentioned scoring 75% on PrepCast and 60% on Study Hall. They noted that the difference was due to the ambiguity of questions, especially in Study Hall.
I’m curious to know if this level of ambiguity is also present in the actual PMP exam. For those who have taken it, does the real exam feel closer to PrepCast or Study Hall in terms of question style and difficulty?
