Mo3 , I know what point you were making and I was agreeing with you apropos UWC. Hence the "yup"!
To the original poster, I agree the admissions staff can be offputting. Luckily they do not deal with your kids in the school.
To cynic, if parents sing the praises of a school what more do you want? Influences on character, ethics and conduct are very difficult to apportion. I guess most parents like to think that they teach the positive traits that their children exhibit. UWC certainly does its bit in building well rounded individuals. I would imagine many of the excellent schools here in Singapore do too. We can only comment on the school our own children attend.
