I didn't get into a top-tier school until late high school, and it cost me dearly in lost opportunities later on. However you decide to handle your son's education, keep him challenged for as long as you can. If you are not into home-schooling (it is quite taxing on a parent), consider hiring a tutor or two. Grad students are cheap and would frequently give a discount or even do it for free for the sheer enjoyment of talking to a smart kid for a change.
I was thinking tutor as well.
Maybe find other home schoolers to share the burden? The parents could trade off days, and a few smart kids together could learn from and challenge each other. I responded to competition from other smart kids.
Although my 8-year-old son likes his teacher, he is frequently bored at school. He attends a high quality suburban public school in the United States. He has a lot of traits in common with LessWrong readers, and we would like advice for what he can do to counter his boredom. Many of you must have found grade school more or less tedious. What were your coping strategies?
