Some of the problems encountered with acceleration in a B&M school are not problems when vitual/home schooling. A kid can move at their own pace, and skip any unnecessary repetition and practise, while avoiding jumps and gaps. The level and pace of learning has no effect on social situation. The room, computer, table and chair are the same. Same house. Same loving family. Just faster learning.

One problem that remains with a (virtually) pre-boxed curriculum is that it's still designed for average students, so you do need to find ways to add depth and challenge.
