Why is the woman here?

M: Hi, Jeanny. Why have you come to school an hour early?
   W: I want to get a front row seat and review one more time before the test because I failed a course last tenn. Why are you here so early, Jack?
   M: I get out of my car here at this time every day. You seem to be nervous about your lessons. Have you finished your review?
   W: I’ve only been studying night and day for the last week. If I don’t get an A in this class, I won’t get the support of my country. Why do you seem so calm?
   M: This class is really just a review for me. I’ve been learning it for two years.
   W: That’s lucky for me.
   M: Jeanny, can you guess what the test will be like? Will it be difficult?
   W: I hope not. But I’m still worried about it.
   M: Well, cheer up. Hope for good luck.
   W: Thanks for wishing me luck. I’ m going to need it.
