What kind of professors do you have that are trying to "trick" you? That's... I dunno, not my experience at NYU. The presumption is you're on top of your shit, but there's no ball hiding. Now that I think of it, the least supportive professor was a Harvard grad (not Miller). They really pull that on you up there?
Well basically this:
I agree with this. A check list, if made correctly, may get you most of the major issues but smaller issues or issues with professor-style finesse will almost never be caught without your own knowledge.
I suppose "trick" wasn't quite the word, but more "professor-style finesse". I just had several: "but wait, isn't XYZ here too, and doesn't it..." sort of thoughts when doing the practice exam and went into office hours to ask about it. He basically told me that the majority of students missed it on the exam, and that it was a sort of like trick/easter egg for students who really got the material. He does it to try to create a larger spread, to make assigning grades to the curve easier. My point is that I spotted it from just knowing the material off the top of my head. There isn't a lot of time on this particular exam--it's an 8 hour take home, but there's legitimately 8 hours worth of exam in it, so not only are you time-pressed, you're exhausted.
