If a kid is bored because they're in a class that's too simple and they already know it all, the problem isn't that the kid is "too" far ahead; there's no such thing, as long as the kid is having fun. The problem is that the class isn't useful or interesting, so they shouldn't be in it. That's quite fixable.
I could have gone to a school for the gifted, but I wanted to be with normal people, not the over achievers (friends that went later told me my worries where justified). At some point I just decided to minimize all school effort and did my own thing as good as I could, but hated school since 2nd or 3rd grade.
I dropped from winning some math competition every now and than to the lowest mark that got me through, but I would do it this way again.
I'm happy with whom (not what) I have become, a thing surprisingly few can say.
