M: Hi! Are you busy right now?
W: Oh, hi, Sean. There’s a meeting at two–thirty, but I have a few minutes. What can I do for you?
M: Well, I wanted to talk with you before I went to register for next semester. That’ll be my last term here ’cause I hope to transfer to the university next year.
W: Great! Have you applied to the university yet?
M: Not yet. The deadline’s not till March 1.
M: But I was, uh, I wanted to check with you to see if there are any other courses. I still need before I transfer. I think I’ve filled all the requirements, but I, uh, just wanted to make sure before I register.
W: All right. Let me pull up your record. Let’s see now … Sean Howard. Here we are. Hmm. All right, it looks like you’ve got all of your English and math credits, so you’re OK there, as well as your humanities and, uh, social sciences. But for natural science … hmm … you took biology in your first year, but I don’t see anything after that. You’re required to have at least one more natural science course before you can transfer.
M: Oh, really? I thought I needed only one science course.
W: No, sorry, you need at least eight credits in natural science, and that means two courses.
M: I didn’t know that. OK. Then I wonder which course I should take. What do you recommend?
W: Next semester … let’s see … it looks like astronomy, botany, and ecology are all being offered. There’s also a course in meteorology for non–science majors.
M: Meteorology? Do you mean, like, the weather?
W: That’s right.
M: Hey, that might be kind of interesting. 1 always wanted to know how they forecast the weather.
W:Then that’s the right course for you. Oh, and, Sean, it looks like you also need two credits in physical education.
W:Right. You’re required to have four credits, and you’ve only got two so far.
M:Oh, boy. Well, OK, that shouldn’t be too hard. Maybe I should take golf that is offered in the spring, right?
W:Golf? Uh … yes, it is. Do you play?
M:Not very well, no. I’ve only played a couple of times, but 1 need to do better than that. My boss plays golf and he’s always talking about it. It would be nice to know what he’s talking about!
W:Then you’d better take golf. You’ve got to play golf with your boss!
M:OK, OK, you talked me into it! Hey, thanks for your time. I appreciate your help, and I’ll get out of your way now.
W:Glad to help, Sean. Good luck with registration!
