This is indeed one of the most scientifically accurate Intelligence Quotient tests. You have 40min to answer 39 problems where you have to select A, B, C, D, E, F, G, H.
Keep in mind that every time you start the test (by reloading the web page) some of the problems get rearranged, so every time the test is a little bit different than the first time.
When you’ll finish click the menu & submit, and you’ll see your real IQ score.
Design and development:
Anders Ditlev Jensen
The test is developed using Macromedia Flash MX. Inspired by Raven’s Advanced Progressive Matrices.
Info from Iqtest.dk : “The test is Culture Fair, i.e. it minimizes the effect of cultural variables, such as language, mathematics, etc. The test is based on logic, but is furthermore designed to test learning capability, memory, innovative thinking and the ability to simultaneously address several problems. The test measures the general intelligence.”
