Did you ever take History 231 ?   Yeah . Last semester .   Who was the professor ?   It was Professor Johnson .   I have him this semester . What do you think about him ?   He's a terrible instructor and demands a lot , but fortunately , he's an easy grader .   What did you end up getting ?   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 .   That's probably because he grades on a curve .   Are you enjoying the class so far ?
