W: Good morning. I’m Victoria Porter. How can I help you?
M: Good morning. My name is Frank. I have to complete the enrolment form, but I’m not sure about some aspects.
W: (19)Let’s refer to the handbook and see how I can help you. What’s your first problem?
M: Well, I can’t decide on which program to take.
W: Do you want science or arts?
M: Arts. But I can’t decide among social sciences, humanities and education.
W: You needn’t make that decision now. (20) You can leave it until the end of the first year.
M: I see. Then I need to select my courses carefully.
W: Yes, First, foundation course. All students must take one foundation course as part of the requirement of the first year. It’s on Page 21. Have you read the description?
M: Yeah, I’d like to do A109 Futures. It looks so interesting.
W: But as a foreign student, I suggest you consider A114 Australia and Its People.
M: What about this, Structure, Thought and Reality, or Life in the Universe? The description of both says they will help me to develop skills of argument and analysis.
W: Actually all the foundation courses are designed to do that. But A114 will help you gain a better understanding of the country you live in.
M: That’s true. And it’s worth six points while each of the others only three. OK, I’ll do A114.
W: It’s very important to keep your points in mind when selecting courses. Normally full-time students enroll for 12 credits each semester or 24 each academic year. However, (21) if your enrolment drops below nine points in any one semester, you won’t be considered full-time.
M: (21)What would happen then?
W: (21)Well, you won’t be eligible for student visa.
