A: "Did you ever take History 231?"

B: "Yeah. Last semester."

A: "Who was the professor?"

B: "It was Professor Johnson."

A: "I have him this semester. What do you think about him?"

B: "He's a terrible instructor and demands a lot, but fortunately, he's an easy grader."

A: "What did you end up getting?"

B: "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."

A: "That's probably because he grades on a curve."

B: "Are you enjoying the class so far?"

A: "I hate it and I was about to withdrawal. But after hearing your experience, I think I will tough it out."

B: "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."

A: "Thanks for letting me know. I feel relieved now."
