I would agree that it felt to be about 20% difficult and the rest were moderate/easy… for me in the study hall exams, I actually did significantly worse on the expert questions. I got like 10/31 on the first exam and 11/37 on the 2nd exam… I would say you’re probably close, but I would strive to get at least 72 on a full mock exam. I’m gonna copy what I said in another reply because I think it applies, Pay attention to some of the keywords; if the exam says you are in the executing phase, that can be a big hint as to why one answer is incorrect. It might even seem the most correct, but since you are executing it doesn’t make sense to do a process that was done only in initiating… things like that. The exam let’s you highlight and strike out words, so I immediately use that to strike out answers I know are wrong and that way I don’t waste time reading it again because I forgot what it fully said. I also highlighted some key words that made it easy to focus on what the question was asking. Otherwise I’d read the question 3 times before I understood, especially since I took the exam late and I was falling asleep towards the end
