A：Did you get your grades yet?
B：Yeah. My whole GPA is screwed up now.
A：Why? What happened?
B：Well, I bombed my econ final and ended up with a 1.7.
A：Ouch. You must be very disappointed.
B：Well, it's my fault because I didn't study as much as I should have.
A：Why don't you re-take the class next year?
B：That's what I plan on doing unless I keep screwing up. How did you do this semester?
A：I didn't do that well either. I ended up with a 3.2 this semester. That drops my total GPA to 3.45.
B：My GPA is pretty similar to yours. I have a 3.1 now because of the stupid econ class.
A：What was your GPA before this semester?
B：I was sitting happy with a 3.4.
A：Why did it go down so much?
B：Let's just say I screwed up more than my econ class.
A：What happened to you?
B：I started playing StarCraft and ended up wasting a lot of time.
A：You better stop slacking off.
B：You're right. I'm not going to play games during school anymore.
