Albert Einstein, arguably the greatest mathematician/scientist of our or any time, was by no means an honor student. School was not to his liking, and he did not excel in his classes. But he was able in spite of (or perhaps because of) that "shortcoming" to successfully nurture an inner genius that was prolific, productive, and formidable. A homeschool environment is perhaps then the most likely option for children whose particular genius does not fare well in the classroom.
