Even small schools are happy for some pointy kids. And while large schools can handle more kids who have only one hat, there is a huge need for “connectors”. Without them, there is no real community and the benefit of having a multi-talented class is lost.
And for those who think these kids are limited so the others don’t feel bad, I have yet to see a single kid who outshone all the others in every academic class, every musical performance, every sport, etc. It takes all kinds.
There are schools with STEM focus, but not these BS. If you want a school that selects on that basis, you’d have to find one of those.
