Recent Macalester College graduate Cuauhtemoc Cruz Herrera hasn't forgotten what it felt like to be an 11-year-old student in a math competition when the playing field seemed tilted against him.
Nobody involved was cheating, by the way. It's just that he was going up against kids who attended private school, with money for math clubs and mathematics teachers. Those were unaffordable luxuries in the public school in his hometown of Guadalajara, Mexico.
"Because of all the trouble I went through to reach the national competition, I told myself [that] in 10 years, whenever I was ready, I was going to do something for kids that were in my position," he said.
Now an entrepreneur and educator, Cruz Herrera has already made a big difference. And way ahead of schedule.
With a little encouragement, the soft-spoken and earnest Cruz Herrera is happy to tell what he called "the long story." It's worth hearing.
It really does begin with that 11-year-old budding mathematics star at a public school in Guadalajara.
A teacher had come to his school to invite children to participate in an upcoming mathematics competition. Cruz Herrera stepped up. Along with some fellow students, he got two weeks of free math classes before the state competition.
He went on to win one of the eight first places, "by luck, plus the work I had done," he said. But things didn't stop there. He was thrust into four more months of preparation for the chance to compete at the next level.
