Is 12 AP classes impressive?

[ClaremontMom]

"in most schools the core courses outside of AP are an intellectual wasteland. "
That is quite a sweeping assumption to make…
More advanced AP classes may have been wonderful for your children, but I dont think you can expect others to agree with your statement, particularly as you have offered no data to support it.

I don’t know about “most schools”, but I do know that my kids avoided most regular classes because they found them too easy and quite boring.
