Hi,
This is a bit of weird question and probably noted somewhere, but I noticed that on mahattan CAT exams the same Reading passage is used and have several types of questions (strengthen, flaw etc) associated
to it.

Is this the case on the real exam? If so how should one make notes, since if you know the same passage is being used more than once, one should make detailed notes first time around, but then again you don't know how many questions using that same Reading Passage will be asked?
