“Also,,,are you admitting that homeschoolers have less wasted time?”
I simply don’t know. Homeschool curricula widely vary, and the proficiency of parents involved varies widely. Clearly you’ve had success, but I don’t think it automatically translates to homeschooling in general, based on my experience with friends and neighbors who homeschooled - with differing levels of success.
“wasted time” is also a subjective term that would depend on the individual student.
You are assuming that those who did not do as well in homeschooling would have done better in government school.
But...it is very possible that they might have done far worse.
