My parents told me that it was high enough and I don't need to know XD. Well, I suppose I'm fine with whatever I got, considering I skipped three grades of school and still ended up in the top 7 people in year 12 :). I know *when* I took the test, I was in grade 3 and I'd get to skip school for the morning and go to this place that dealt with gifted children, and play games with pattern matching and stuff XD. Well, that's what it seemed like at the time. It wasn't until much later that I realised all that fun stuff was an IQ test.
I believe that test *is* timed though, it passes a session ID so I think it keeps track of the time between loading and submission. It does talk about timing on the page.
