unconventional motivation

The drive to study for tests and quizzes in college so that you can work quickly and leave the testing site as quickly as possible.

Chris: why the hell are you studying?
Billy: Chem is my last class tomorrow, so I want to get out of there as soon as possible. Also, I want to miss the rush of people all turning in their quizzes at the same time.
Chris: Ahh, classis unconventional motivation.
