#Person1#: Hey John, did you register for classes yet?
#Person2#: I register this Friday.
#Person1#: What classes do you plan on taking?
#Person2#: I really want to take the communication class, but I don't know if it will be available.
#Person1#: Is that class really that popular?
#Person2#: Yeah. I tried to get in last semester, but it was full by the time I registered.
#Person1#: What other classes are you going to take?
#Person2#: I still need to take English 201, but I really don't like writing.
#Person1#: I took that class already. There is a lot of writing, but it's not that bad.
#Person2#: Oh really? Who was the instructor? There are like 4 different instructors to choose from.
#Person1#: I had Professor Mahoney.
#Person2#: Is he an easy grader?
#Person1#: I'm not sure if he is or not, but I thought he was definitely fair.
#Person2#: Do you mind if I ask you what you got?
#Person1#: Not at all. I got a 3. 8.
#Person2#: Well, what did you get in English 101 last year?
#Person1#: I got a 4. 0 in that class.
#Person2#: Well, I can't compare to you. I got a 3. 1 in English 101. That means if you got a lower grade in English 201, it must be harder.
#Person1#: It's not what it appears. I actually tried harder in the 101 class. If I put as much effort into the 201 class, I would have received the same grade.
#Person2#: Oh. That helps. Thanks.
