Is anybody out there did any of these passages? I was about to do it, but found out it is very diffcult. Are these questions reflecting the diffcutly of the real test? Thank you!

They are supposed to be pretty representative.

I would always assume practice materials are easier than the real thing, but maybe that's just me.

did you do it?

I have done some of the Khan passages, yes.

I am working through Kaplan first and doing Khan closer to my test date, since Khan is supposed to be closer to the real thing.

Yeah I started doing them recently. They are surprisingly pretty tough, and this coming from a chem major; I've had far better success with the old TBR passages.
Having said that, it seems pretty good practice - and best to get beat up now than on test day.
How are you guys approaching the passages? It's hard to mentally map the passages and the questions seem to involve a lot of novel reasoning based on the passages. Also, are you guys timing them?
