Miraca Gross' "Exceptionally Gifted Children" provides quite detailed synopses of the education each of her EG+ students achieved. In the cases of a few of the most gifted children, early and significant suppression of learning was associated with underachievement, behavioural problems and, in one case, early abandonment of school.

I'd recommend the book. It's an interesting set of case studies.

What is to give light must endure burning.
