not sure on %s, but be wary of remembrances. I've heard from numerous qualified sources that during the exam, individuals would clearly recall seeing ?s from previous remembrances, and about to choose a particular [known] answer, but then realize that the ?s was actually spun a bit differently and that the true answer was indeed a different one. talking about messing with your head. i think this is meant to deter folks from simply memorizing remembrance answers.
all in all, i figure just do you your part in studying, pray before the exam that all goes well, and have a drink after it's all over.
