Most of those “genius” kids described by OP daughter’s friend are most likely hard working HS kids with above average IQ. They have perfect GPA, test scores etc, not because their IQ, but because they also work hard on top of their IQ. Most likely none of them will grow up to be those once in a century genius who change/influence the path for mankind. If they can continue with their drive and motivation into their future careers, they will likely be contributing to their field of choice steadily and surely. Nothing negative about them. On the other hand, getting perfect GPA, test scores, going to Ivies are not indicative of being more successful contributing to society. There are so many other factors, including IQ, passion, hard work, luck, maybe even EQ, that are part of an unknown formula for one’s future path.
The OP daughter’s friend can have a very successful path if she is determined to find one. First step is to get off this Forum and become/continue being active in her school/community
