“Sounds like they have never heard that intelligence is a hereditary trait”
I come from a family of b and c students, myself included. No real academic standouts.
My wife was her HS class valedictorian, tested out of her college chemistry and biology classes and was #1 in her veterinarian class.
Her dad and mom both had engineering degrees back in the 40’s.
My wifes brother was an engineer and also tested out of many of his college classes. All his kids are top of their HS classes as well and one has a full blown scholarship to Yale.
Yep genetic.
