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. He couldn't have guessed his way to that IQ. Your son is PROFOUNDLY gifted. Full stop.
Now, as for his performance in school/academics - that's not always going to correlate directly to IQ. Achievement is a combination of exposure and effort. His lack of desire to do anything "hard" is something very common (at least on these boards, it seems) among kids who are under challenged in school - they develop a sense of perfectionism. "This is easy, I should get a 100/A." At this point in life, he's probably hardly learned anything from an actual teacher. He's capable of absorbing things like a sponge and understanding them immediately. I think home-schooling him and getting him to do challenging work is an excellent idea. He doesn't have to be working at any specific grade level - he just needs to be learning and understanding what it means to put in actual effort in his schooling.
