She never stated that his 34 made him brilliant. (otherwise my kid would be brilliant also… Well… He’s smart… But common sense deficient ?).
It was the way he is thinking at a young age. I personally don’t think that makes him brilliant either but maybe the OP should have him tested for a gifted school that would challenge him. In Chicago there are summer schools for gifted kids like part of Northwestern University. My kid did a year of stats in 3 weeks with 12 other kids and thought that was the right pace and fun. Lol…
