If the school forces too much homework or useless subjects on children, conscious parents can respond by being more lax and accepting less than perfection from their kids. In this system (school-child-parent-exam), the parent is the only flexible link. As parents we don't have to be hard on kids that don't want to do homework or don't to great on some subjects.
My own life experience tell me that success in elementary school does not equate with success in life. In fact even high-school and sometimes college are almost irrelevant to the kinds of tasks people have to solve once they get hired. It's more important to be creative, curious and passioned about something.
