I don't agree with these ranking.

It depends on pupils studying in the school. That is how the school can grow to be a better school.

But, most of the schools are really good. this ranking can be very useful to parents who would want to send their child to primary.

Are the schools equally good in sports and arts? To be the best school, it must be balanced in every subject, or if possible, better than every school in all subjects.

NEway, thanks for the information!
