L: Yes, this is the Faculty of Engineering. How can I help you?
S: I know there was an orientation meeting last Friday, but I did not attend that meeting, so I’m wondering if someone could give me some information about... you know the campus life or course requirements or something like that.
L: Yes. Sit down, please. Where should we begin?
S: Firstly, how many lectures do I have to attend every week?
L: You know there are not too many lectures of postgraduate courses. Let me check.  Oh,you
have lectures on Monday, Wednesday and Friday afternoon, from 2 p.m. to 4 p.m.
S: How often do I have to attend seminars in a week?
L: Well, there is only one group seminar on Thursday morning at 9 o’clock.
S: You mean the group?
L: Yes.
S: How many people are there in one group?
L: About 3 to 5.
S: Fine.
L: You will discuss about 20 minutes and then the representative of your group will give a short presentation.
S: A presentation?
L: Right.
S: Do all members in the group have a chance to give a presentation?
L: Maybe. And then your subject advisor will give you a mark.
S: A mark? Does that mean the representative’s mark is all members’ mark?
L: That’s right.
S: How about attendance?
L: The postgraduate attendance is only 70%. But a few students will be absent in our faculty.

L: You have three modular courses from September to June next year.
