Depends on the teacher I guess, but we never got corporal punishment unless there were grave discipline issues like beating girls with snowballs or weaved scarves. Math? No. You just got a bad grade.

Most of our olympics are currenty researchers abroad or tech leads in the country. Entrepreneurs not so much, maybe the networking types.

The hardest math problems we encountered were from the USSR olympics. There was a magazine with math problems which collected such gems.
