I’m sorry for you bad experience, but statistically kids do better when homeschooled. It’s not like public school as some minimal level they’re assured to bring kids up to.
Beyond studies by the National Home Education Research Institute, that is. The three leading studies by homeschooling advocates looked at "homeschooled students who went to college" and how they did at school versus public schooled students at college, and ignored the fact that the percentage of homeschooled students who went to college was much smaller (why?) than for public schools.
