M: Hello, can I help you?
W: Oh, yes. Good afternoon. I saw the advertisement of your centre. And I was wondering if you could tell me a bit more about the courses you are running. You’re doing the computer software courses, right? Are they just for beginners?
M: No, we also have one for medium level and we may offer advanced level as well in the future. And each course has three parts. The first part is word processing. The second is about the use of databases. And the third one is a little more complicated, which is about how to create and edit a new program.
W: I see, and when are the courses held, please?
M: The computer room opens from 9 a. m. to 9 p. m. on working days and from 10 a. m. to 5 p. m. on Saturday. As you can see, students can’t just listen to the lecture for 12 hours. Actually, it’s common that you will spend most of your time studying by yourself. The tutor will give you some brief guidance at the beginning of each course, explain everything you need to know and need to practice. As the course starts from the very basic level, you will not have any problem.
W: That’s good and when will the next course start?
M: Let me see. Oh, it’s June 12th. However, if you decide to enroll in this program, you should come to the class on time, or you will miss the most important part of the class. Although most of the time you practice by yourself, you do need the essential guidance.
W: Hmm, by the way, how long does the course take?
M: On average, the book takes 20 hours to be completed. We expect you to attend the class at least six hours a week, so that will be about 4 weeks. (8) But if you can’t attend at regular times, you should let us know, because we reserve the right to keep the place open, which means your place will be given to someone else.
W: OK. Got it. Thank you!
M: My pleasure.
