Just a tip, if you're not enthusiastic about doing this essay, there's really no point in doing it. Doing a good job might win you some money. The way it works is you hand in your essay during a small group discussion with a few other people from your dorm. You really just put it in a pile and they read them later, so as long as you give them something it doesn't matter.
If you're feeling especially creative, you could write a joke essay, it might give the readers a laugh. Might I suggest the topic, "The Wrath of Grapes"?
