Study session in high School was good. In college it was pointless. We were in the same room as the football players and tennis girls. The football players were always getting all loud talking to eachother and jacking around. Could have spent better time some place else.
I think it you start kids early that isn't bad, but it you start yelling at them or pushing them that is when they break. The kids often want to lean on their parents to keep going, but some parents think they need to be pushed.
