I agree with the above post, I haven't come across any passages that are "insanely hard" yet, some of them are downright easy. Are you doing content review before you do the passages? If you're not I could see how the passages come off as insanely hard. A lot of the "hard" questions end up being very easy through process of elimination; they like doing questions where the three wrong options essentially mean the same thing, or are part of the same process, so even if you no idea what the question is asking, via p.o.e only one option will make sense.
