What is sounds like to me is that none of these children are gifted at all. That's why you're talking about 'overcoming a challenge.'Believe me, when one is gifted, nothing is difficult.

When my daughter and I did 2nd year math at college in San Diego, the tutor told us he had a masters in math from UCSD, and he had never seen anyone do math like my daughter and I did. We could learn something in an hour and write an exam on it an hour later in half the time required and get 100%. It wasn't difficult./
