You've just reinforced all my own prejudices.
No science before college.
But, also, no graduating college without 4 years.
K-12 teach concrete stuff like anatomy, maybe some "isn't nature neat" but stay away from biology and chemistry as science. Maybe some simple mechanics from physics.
Don't get me started, I can spew forever on this.
And in ten years you would have the US become a third rate nation. Gag.
