This kind of jackassery is why no less than 30 public schools in my county are slated for closure.....parents demanding better learning by home schooling or transferring to private schools.
I went to public school in the 70s and back then my school system actually prepared you to at the very least go to junior college.
I graduated high school (NJ) in ‘69 and headed to college to study engineering. As a freshman, I found that calculus was required for physics. Having never heard the word ‘calculus’ in the public school system, it was ‘learn as you go’. At times I had to study ahead of the class to pass physics.
Interestingly, in the ‘50s, CA had one of the best schools in the country. They improved them so much it’s now near the bottom.
The big problem seems to be too much homework and GRADES!
