answer: Harry stays up preparing for the exams because he didn't do much last term. #Person1# feels unnecessary staying up studying and advises Harry to have a week off, but Harry disagrees.
documents: #Person1#: Hello, Harry, you look terrible! Have you been to the doctor's?
  #Person2#: No, I'm not ill. I'm just a bit tired. I'm probably not sleeping enough.
  #Person1#: You shouldn't go out so late then.
  #Person2#: I'm not going out at all, actually. I'm too busy studying.
  #Person1#: Studying? But the exams aren't for another 2 months yet.
  #Person2#: I know, but I've got a lot to do. I didn't do much last term. I wish I'd been more like you.
  #Person1#: Well, yeah. I went to every lecture and I took lots of notes, but that doesn't mean I'll get good grades. At least you don't get nervous in exams like I do.
  #Person2#: Have you started revising yet?
  #Person1#: Not yet. I'll probably start next week. But I'm not going to stay up all night doing it. That never does any good. I might work until midnight a couple of times, but that's all. Anyway, you should have a week off.
  #Person2#: I don't think so. I can't afford the time.
