If you see Britt Casey walking the halls of Farmer School of Business (FSB), you might think he was just like everyone else — just another junior marketing major, rushing to lectures and hoping to do well academically.Even if you share a class with him, you might not notice that he reads ahead in his textbooks and asks for assignments weeks in advance. And you almost certainly wouldn’t know that he works because he leaves Oxford in the middle of the week to drive race cars.
