Well, I agree with the repetition in math in many schools. That can be a big problem for eg/pg kids. It's been an issue with DS7. For other subjects, like history, he wants the breadth and depth, but with the math he doesn't tolerate that repetition with the worksheets.
At least with homeschooling, you can use a general curriculum guide/series and avoid a lot of the repetitive math. Those worksheets can be pretty mindless and some kids are ready for higher level much earlier than most schools can accommodate.
It can also be a physical/logistical problem with the way our schools are arranged too. A young child may rapidly accelerate through K-5/6 math curriculum but then be unable to attend an algebra or geometry class with middle or high schoolers because they're literally in another building across town/city.
Like I said, there's a lot of variables and each year seems to change. I've found it helps to be flexible and have an open mind. It's not easy to say the least.
I like Supercrunch's idea of dropping them off at the LOC for about 10 years. That gets my vote.
