Case of Senior-ites

I've got a test this evening and man I've got a big case of senior-itis going on. How many ways can you rehash Future Value and Present Value formulas?

A scene from Ocean's Eleven keep popping into my head, the one with Danny and Rusty driving in a car and the dialog goes something to the effect of

Rusty: God, I'm bored!

Danny: You look bored.

Rusty: I am bored!

Oh well you gotta do what you gotta do.
