There was a study done in a place quite unexpected to me now, and interesting back then when I was in school myself. My Math Teacher told there were some schools where a pilot was conducted teaching calculus concepts from 5th,6th std students and were monitored till they did their graduations and career paths. Interestingly the people who were chosen randomly, performed equally well and their decisions in addition to math were more logical. This study was done in India :)
