Then it is wrong school. But the other issue is that you are strongly drawing here on the stereotypes - that this school will be test obsesed, kids in it will be bad entitled kids and you cant make friends with them.

Kids in real world selective schools do form relationships, are curious, interact and like the world outside. Some selective schools are like you describe ... but others are not and kids in them are happy.

The type-A kids are friends with type-A kids, yes. Everyone else is ostracized. That's what gives rise to stories of "entitled, can't be friends with them".
