W：Hello，Parkson college．May I help you?
M：Yes．I’m looking for information on courses in computer programming．I would need it for the fourth 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：Aha．Have you taken any courses in data processing?
M：No．
W：Oh．Well，data processing is a course you have to take 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 seven to nine forty-five．
M：Oh．Well，that’s all right．I could manage that．How many weeks does the course last?
W：Mmmm，let me see．Twelve 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 three hundred dollars including the necessary computer time．
M：Aha．Okay．Ah，where do I go to register?
W：Registration is on the second and third of September．between 6 and 9 in Frost Hall．
M：Is that the round building behind the parking lot?
W：Yes．That’s the one．
M：Oh，I know how to get there．Is there anything that I should bring with me?
W：No，just your checkbook．
M：Well，thank you so much．
W：You are very welcome. Bye!
M：Bye!
