Honey... his IQ is 150. That's.... massively rare and practically off the charts. It's unlikely he'll ever come across another child his own age within a full standard deviation of his IQ - that's how rare it is.
Basically everyone in my gifted pullout class was within "a standard deviation of 150." since you only became eligible at 135 and I don't recall anyone who was significantly below 140 (since we eventually compared IQ scores).
There were plenty of us, generally 140+, IIRC.
Isn't 150 only at about 99.9?
