Oh professor, I am sure I can get a better grade...

The exam that we had, you were kind of tough on, you know, grading our papers, don't you think?

I mean, I got a D and I think I should have at least gotten an A- at least.

And I really just need to pass this class and you're just really tough on me.

Vena, in order to get a better grade, to go from a D to an A+ you have to apply yourself, you have to study.

Put some effort into it. The rest of the class does.
