“Hey Professor. I’m trying to study for the exam, so I was wondering if you could, like, tell me about just the stuff that’s going to be on it so I can study better.”
“No. That’s not fair to the other students in the class.”
“Oh. Well, is there any way you could like, I dunno, tell me the what things from the book are the stuff I need to know for the exam?”
“Yeah. I do that every day. It’s called class.”
