Dialogue: W: You said you wanted to talk to me about that course I'm doing this term. Music? M: Actually I was a bit confused because I thought you were majoring in maths. W: That's right, I am. I'm doing four months courses this year. Music is an optional course - you just choose it if you're interested. Why? Are you thinking about doing it? M: Well, I'm not sure. What are the requirements? W: Well, for a start, it's distance learning - you don't actually have to be at the university to do it. M: I'm more worried about the actual musical things. Like, I don't know how to read music. W: That doesn't matter. You'll learn as you go along. What about computer skills? You're OK there? M: Yes, of course. Does that matter? W: Yes, I'd say they're necessary. Like I said, it's all distance learning, so it's computer-based. Question: What is the man worried about? - Distance learning. - Maths problems. - Musical knowledge.
