> Who said anything about segregation?

Saying that student A must attend school B because of trait C and student X must attend school Y because of trait Z, is segregation. It just so happens to be based upon you deemed "educational qualities" rather than what we normally think about, race. Or more economic status.

> I think kids/parents should have free choice about which school to go to: advanced/normal, where the school just makes suggestions and the parents can opt-out or in freely.

We already have free choice. There are a myriad of private schools you can choose to send your children to. Pay the fees and send them.
