gavra,
I dont think PPY is currently capable of housing so many students, but aside from that, it’s not that it’s not a community school. It just belongs to a different community. I don’t think its realistic for all those parents to conform to the rules of PPY. This is just my opinion.
When you say BYOB is a community school, I think you’re right. But I can’t think of another school that would be considered one offhand.
