W: Mary speaking.M: Hi, it's Robert. How's it going? Are you ready for the maths exam tomorrow?W: Just about. How about you?M: That's why I called. I thought you'd be prepared, and so maybe you could help me. I'm quite worried. I think I know how to use mathematics formula, but we weren't taught the derivation. Do we have to know them?W: I wish I knew, but I'm afraid I'm not sure myself. Just get a good night's sleep and don't worry. That's what I'm going to do.M: But can you tell me how to derive them, just in case?W: Look, I'd like to help but the formula for that is long and complicated. But you can look at my notes in the morning if you want.M: That will do. I think I'll skip the sleep. Mai thinks the exam might cover last year's geometry. Did you hear anything?W: Well, I try not to listen to what other students say. Mr. Davidson said it would only cover this year's work.M: But surely they'll try to trick us by throwing in some things we aren't expecting. I'd like to go over everything again.W: Look, Robert, good luck. I have to get my sleep now. Stop worrying. See you in the morning.M: Sleep! How can you! I think I'll make a big sandwich and get back to studying. See you, and thanks anyway.
