I had a real one after a stroke to measure my deficits/damage. A neuropsychologist administered the test. It had oral and written parts. It also had pictures. It took about five hours to complete it. It was extremely detailed, measuring IQ in math, language, reading, problem solving, etc. What was interesting to me personally was to see my IQ #'s in areas of known brain injury vs non injured area. It was like having two sets of numbers. A bit scary too. I wouldn't waste time with on line IQ tests. They can't possibly get the detail or analysis to tell you much that would be valuable to you.
