听力原文：W: Hello. M: Hi, Jill. This is Joe. W: Great to hear from you, Joe. How have you been doing? M: To tell the truth. I'm very worried about our final exams next month. For one thing, I can't sleep. W: I went through the same thing last year. M: That's exactly why I'm calling you. Do you have any suggestions for coping with anxiety? You know how I hate exams. W: Well, last year the university offered a stress management course at about this time. Have you been in contact with the student help services? M: No. I haven't had time. W: Funny, isn't it? Just when students need help most we can't afford time to get it. M: Well, perhaps I should find out more about this stress management course since I' ye got to get better. W: I suggest you call the health services tomorrow. They open at 9 a.m. W: Best of luck. And have a good night sleep. M: That's easier said than done. What is the main topic of this conversation?
