Deep IQ Assessment
134 questions in six timed sections, about 53 minutes. Six index scores and a full-scale IQ estimate, the way professional batteries report.
Our most complete test. Like the WAIS, it scores six abilities separately, so you learn not only how well you reason but where your strengths and weaknesses lie.

Questions people ask
Is there a long, complete IQ test?
Yes: the Deep IQ Assessment. 134 questions in six timed sections, about 53 minutes, close to the length of a professional battery. It reports six index scores (fluid, quantitative and abstract reasoning, visual-spatial ability, working memory and processing speed) and a full-scale estimate with a 90% range. Progress is saved after every section.
How is my score calculated?
Correct answers are adjusted for guessing and converted to the IQ scale (mean 100, standard deviation 15). Until 200 people have taken our tests, you are compared with a provisional norm. After that, the difficulty of every kind of question is measured on real test-takers and your score is placed on that measured scale. You always see a 90% range, not just one number.
