It would be great if skipping grades became more commonly acceptable, especially for the sake of children whose parents don’t have the wherewithal to get them advanced instruction (either through own knowledge or money). I would have liked to skip a grade in elementary or middle school, but instead ended up in the back with an algebra book - from which I taught myself the parts I was interested in, but glossed over the parts I didn’t like. If I’d been able to skip a grade, I would have been forced to sit through all of it, and that would have been a good thing.
