What are the speakers mainly discussing?

W: Hi, Vincent. What are you doing here?
M: What does it look like I am doing?
W: Well, it looks like you are watching television. (7)But we have a linear algebra mid-term tomorrow, so I thought you’d be studying for it and maybe I can study with you.
M: (8) Oh, well, I was just taking a break. This linear algebra stuff gives me a headache if I work on it too long.
W: I see. I’ve been working on it for three hours already. I’d been theorizing about the sample problems. I just don’t get some of them.
M: (9)But I can’t believe you are coming to me. I mean you do know what I got on the lastTEST, don’t you?
W: Yeah, I know. You told me. (9)I just thought two heads might be better than one.
M: Yeah, that’s a nice idea. But... you know, I wish I knew that person in our class who got a hundred on the lastTEST. She didn’t miss a question. Umm... was it Jennie?
W: Oh yeah, Jennie! She is a friend of mine. Why don’t I give her a call?
M: (10)What! At this hour? It’s already ten thirty. I don’t want to impose on her.
W: Yeah, But let’s at least give her a call and see what she says. Maybe going over some of the problems with us would help her review the material.
