Yeah, I did mine at 7. I was having behavioural problem too apparently. Got really bored at school so I got in alot of trouble. So they did an IQ and behaviour test at the same did. Got 135 and was found not to have ADD/ADHD haha. So Mum wanted to put me up a level but the school wouldn't let her, so they put me up two levels for english and maths and I had to do all the grade 3 art and PE things, so I was never in my actual class. The next year I did grade 3 again. Go figure. And the school wondered why I was such a menace...
So the average score on this thing was 116, the 'average' intelligence is supposed to be 100. Lol @ Nine and it's target demographic.
