And also the competition to get into good school etc.
Basically a student life doesn't start at 18, 16, or 12, but 2years old, if not one and half (interviews for kindergarten).
Constant ranking, placement exams, number of school hours etc makes western education pathetic.
At the end of P1, Chinese kids are supposed to read something like 800 Chinese words, write 60% of them (if my memory serves me well), in France/Switzerland, most kids can barely read at that age. And poor them if you even think to enforce that. We are destroying generations if the parents don't realize how fucked up is our system: education is a building process, with layers and layers of foundation.
