answer: #Person2# tells #Person1# the professor of History 231 is demanding during the semester but gives better grades than test scores. #Person1#, who at first wants to quit the course, feels relieved.
documents: #Person1#: Did you ever take History 231?
  #Person2#: Yeah. Last semester.
  #Person1#: Who was the professor?
  #Person2#: It was Professor Johnson.
  #Person1#: I have him this semester. What do you think about him?
  #Person2#: He's a terrible instructor and demands a lot, but fortunately, he's an easy grader.
  #Person1#: What did you end up getting?
  #Person2#: I got an A -. Sounds good, but none of my test scores were that high, so I don't know how I got a decent grade.
  #Person1#: That's probably because he grades on a curve.
  #Person2#: Are you enjoying the class so far?
  #Person1#: I hate it and I was about to withdrawal. But after hearing your experience, I think I will tough it out.
  #Person2#: Yes. Definitely stay in the class. You will get a better grade than your test scores. He does that deliberately to make all the students study a lot.
  #Person1#: Thanks for letting me know. I feel relieved now.
