IQ Test (NASA)Overview
This is not an "entertaining" IQ test, it will never tell you that you're a genius if you actually aren't one. But don't be discouraged, it is OK to be normal. You will have 40 minutes to answer 20 untrivial questions. The questions are difficult, most of people won't answer more than 7 questions. You can skip questions to complete them later.
