What does it take these days to get into a competitive school?

I apologize for doubting your authenticity. There was one aspect I failed to consider, but now more makes sense.

BTW, it’s not that hard to figure out which HS your son is attending. Not that it matters. However, @jym626‌ is correct; the guidance staff there should be much more able to guide your son in to one of your desired schools than we are.
