I have to agree with Paul there.
Correct tests are 1-on-1 only, timed and will give you three scores. Your median is meant to be your "IQ", although the range can be quite wide bewteen your low score and your high score.
My last IQ test took 2 hours, my high score was a 134, my low was a 112 and the middle was 127
which gives me a score of 124.33 . This was for my ADHD test..which I have. I'm told that I failed because of my auditory retention factor. Got a few tricks to use to help out.
I take notes all the damn time....even if I never look at teh notes again, my retention goes from about 45% to about 80% ecause of the visual aid. Mnemonics work great as well, especailly for names.
My Internet IQ tests tend to be over exagerated because they are 100% visual.
