W: How did you do on the exam?
M: I didn’t do well. I barely passed. The essay question was the worst part for me. How about you?
W: I did all right on everything except the essay question, too. I wasn’t really prepared to write on that topic. I didn’t think it would be on the test.
M: Me either. I thought for sure he would ask about our life on campus. Do you know how much the exam counts towards our final grade?
W: I Suppose it’s thirty percent.
M: Thirty percent! Oh no, I’m in deep trouble this time! That means I’ll have to get A’s on everything else to get a decent grade.
W: That may not be too hard. We’ve already gone through most of the readings the class is supposed to cover. After next week, it will just be review. But then there is the final paper, of course.
M: Yes, I was hoping to do well on this test so I could relax when writing my paper, but it looks like I’ll have to start preparing to write that paper.
W: Well, I will too. Hey, I’m sort of hungry. I think I’ll go and get some lunch. Do you feel like joining me?
M: I’d love to, but I have to go home and study. I’ll call you later.
W: OK, see you later.
