I don't understand this obsession with tutors. If the kids have good teachers at a school with high standards, the only time for tutors is if the kids need remedial help. I'm speculating this focus on tutors comes from the belief that rich kids can achieve at higher levels only because they are getting something extra. I think there is also an underestimation of how much more demanding the better schools are.
