What is the conversation mainly about?

W: Hello, Tony. You must be happy. After all how many students can be so lucky that have been accepted at their first and second choices?
M: Yeah, (4)but I haven’t decided which one to choose.
W: Well, it looks that you have doubts about the state university. But its the chemistry department has a fine reputation. What more could a chemistry major want?
M: Yeah. And they also have internship for seniors. (5) But a teacher told me that for the first two years some lectures have a hundred and eighty students. You probably wouldn’t get to know any of your teachers.
W: Well, you might actually. Because those classes also have small discussion sections twice a week, and have no more than twenty five students.
M: I know. But I’ve heard that they are usually taught by graduate students. At Blue Stone College all classes are taught by professors.
W: Do you prefer a small town like Blue Stone or a bigger place like the state capital?
M: That doesn’t matter to me. (6) What I do care about is just getting individual attention from the faculty rather than making friends.
W: It sounds to me that you are learning toward Blue Stone though?
M: I am. The only problem is that Blue Stone’s tuition is really high and I’m not sure I can afford it.
W: You could still apply for a student loan or sign up for a work-study program.
M: Yeah. I think I’ll look into that.
