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.

We regret to inform you that due to the deprecation of Flash, the current version of the IQ test isn’t readily available, except in the case of very old browsers that still have Flash installed. However, we are working on developing a new version of the IQ test that will be compatible with modern web browsers. We appreciate your patience and understanding during this transition, and we look forward to presenting you with the new and enhanced IQ test in the near future. Stay tuned for updates.

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.”
