I bought my first property in 1966.
Family next door had 4 kids. 3 were middle/high school when I moved there.
I had heard all my life about how GREAT the California schools were.
They went to the store for me-—and when I gave them $$$ in advance-—the high school girl COULD NOT MAKE CORRECT CHANGE for a dollar. I AM NOT KIDDING.
I went to a one room school in rural Wisconsin with 14 kids—8 grades—1 teacher who had 2 years of college.
When I went back to college night school to get Accounting classes-—I was NOT the smartest one in the class-—I was #2 with a 4.0 grade in every class I took.
Nowadays, HS students transferring from CA to Texas find themselves 1-2 years behind their peers here.
