W: Hi Stan, where have you been?
M: Oh, just at the Student Union office trying to see if I can catch you there. I also tried to find out if professor Steinfield has any old exams from years ago.

M: Yeah... you ace all your subjects. But the exams change from year to year, don’t they?
W: True, but the style is pretty much the same from year to year.
M: So tell me all about the process of prostaglandin. I can barely even pronounce it, let alone explain it.
W: Hey, I am no expert but what she’ll be mainly looking for is that you know how it affect the digestion, reproduction, and immune systems.

W: Well, it’s probably because you have too much prostaglandin. Aspirin blocks prostaglandin production.
M: Well, I’m sure it’s this Biology class that’s doing it.
W: Hey, I’ve heard you’re no slouch at poetry. You get me through my course in 19th century poetry and I’ll make you an expert in Biology.
M: It’s a deal. Where shall we begin? Poetry is up my alley.
