I think all you're going to get is a very rough ballpark with IQ scores. Like if that test gave me a score of 146 then I'm going to consider myself somewhat more intelligent than someone who scored 80, but I certainly wouldn't presume I was more intelligent than someone who scored 120-130. Sometimes I get the dumbest stuff wrong and have serious doubts about my ability to think. I showed signs of that when I was a kid. I remember up until the age of 5 or 6 I had the whole concept of money totally ass backwards. I thought that if something was $10 and you only had $7, then you would pay $7, get the thing and receive $3 in change. Now if that isn't a sign of abject cluelessness then I don't know what is....
On the other hand, a child psychologist once told my parents I was a genius. It all stemmed from when I was about 3 and announced that I was going to jump off the garden wall. My dad told me don't be stupid, you're not a bird and you don't have wings. And apparently I thought about this a while, and then replied "yes but I was a bird before I was born. I used to have wings." He mentioned this in passing to a child psychologist friend, who told him that for a 3 year old to come up with such a response, he must be a genius. Why this must be so, I have no idea and it all sounds dumb to me now. But the upshot is that the label stuck and I've been disappointing my parents ever since....
