Hi guys. I have scored quite well on a few IQ tests lately, and was wondering if they are just a sales ploy or actually accurate. They always seem to offer a more complete version that sub-catagorises the info, and elaborates on your intelligence for 9.95. Are these free tests somewhat accurate?
Just to narrow it down, the tests took about 20 minutes and comprised of about 40 questions.
there were no really difficult equations, just pattern recognition and word association, and a few picture based questions.

I studied these in my stat course. If you get different questions everytime you start your test. Youll have to take the test 10 times then calculate the 'ecart-type' i think it is the same in english as in french. YOu have to divide ecart-type by rout3 then multiply it by 1.28.
You calculate the average then you do average (of 10) + - the result you got.
Youll be sure at 95% that your IQ is situated between average-result and average+result.
Reading it again dont make much sense but if you want to do the test 10 times and send me your 10 values ill tell you what's your iq.
