W: Hello. Klarkson College. May I help you?
M: Yes. I’m looking for information on courses in computer programming. I need it for the fall semester.
W: Do you want a day or evening course?
M: Well, it would have to be an evening course since I work during the day.
W: Uh-huh. Have you taken any courses in data processing?
M: No.
W: Oh, well, (19)data processing is a pre-requisite course. You have to take that course before you can take computer programming.
M: Oh, I see. Well, when is it given? I hope it’s not on Thursdays.
W: Well, there’s a class that meets on Monday evenings at seven.
M: Just once a week?
W: Yes. But that’s almost three hours, from 7 p.m. to 9:45 p. m.
M: Oh, that’s all right. I can manage that. How many weeks does the course last?
W: Urn, (20)Let me see. 12 weeks. You start the first week in September and finish.., oh, just before Christmas, December 21st.
M: And how much is the course?
W: That’s $ 300 and that includes the necessary computer time.
M: Uh-huh, OK. Urn, where do I go to register?
W: Registration is on the 2nd and 3rd of September, between 6 p.m. and 9 p. m, in Frost Auditorium.
M: Is that the round building behind the parking lot?
W: Yes, that’s the one.
M: Oh, I know how to get there. Oh, is there anything I should bring with me?
W: No. (21)Just your checkbook.
M: Well, thank you so much.
W: You are very welcome. Bye.
M: Bye-bye.
