Carlos Sainz was the kind of student who made even the teachers groan.
Not because he was difficult, or lazy ... quite the opposite. He was too enthusiastic. The type to raise his hand before the question was even finished, to argue with the textbook, to write extra credit essays for fun.

Every leaderboard in school had his name on top.
Every class, he sat in the front row ... spine straight, tie perfectly knotted, pencil case color-coordinated like his life depended on it.
