Hi, ithink that the only really serious IQ test (they're not that serious really) you can get on the internet is on http://www.iqtest.com/ they ask you questions instead of showing weird geometrical figures.
By the way, my score is 149, and i'm thirteen!!! Of course, they'll ask you your age too. Don't put a fake e-mail for security, they won't send adds, and you'll get your answer by e-mail.
Yeah, i think you're right. But, Even if its better to speak english well for the test, its not a bad one. Better than sorting out colors and geometrical figures!!!!
Anyway, Have you seen the "IQ test, I suck!" thread??
you may get an idea of how some tests are.
