The week of exams was stressful for everyone in Gryffindor Tower. Partly because the OWL and NEWT students were freaking out and snapping at everyone that spoke louder than a whisper, but also because everyone else was taking exams, too. The first-years were especially obsessive about it, among people who were not taking Life-Outcome-Determining Examinations (Percy kept calling them that). Though it had been long enough that they all had started to consider their studies a natural part of life, they were still thinking about Hermione Granger, and they'd ended up doing math about it. Fred and George had observed, with some amusement, that the first-year Gryffindors tended to solve problems they didn't understand by looking at them and saying, "Okay, what would Hermione do?", which usually ended in them going to the library.
