I mean it greatly depends on the quality and dedication of the parents doing the homeschooling.

I never considered it for my kids because our public schools are pretty good, and I did not feel I had the experience or resources or time to do any better. But some people have more of a passion for it and find answers to those issues.

I'm sure there are kids who are poorly homeschooled, but your anecdote does not meany anything in the big picture. Shall I tell you about all the public-school kids I met who ended up flunking out of college?
