Is sending children to famous schools essential?

Your aunt is very sensible. When a child go into a school were their are children who is more advance this child becomes irritable and their whole demeanor change. I think your Uncle needs to listen and send that child to a school where he will be more comfortable so he will learn more. In these famous schools whether it is prep, primary or high they tends to let the slower ones lost in the system. Yes every parents wants there child to attend a famous school but they must always tried to do what is BEST for that child.

Yes its very much essential...
they will be exposed to brighter conditions of the life

I don't think it matters whether or not the school is famous, just as long as it is a good school. People who send their children to "famous " schools often mean well, but they are mainly seeking status. I think that any school is OK as long as it is a good school. It does not have to be famous.
