IQ Tests

This 21 question untimed test is designed to measure your mathematical abilities and knowledge as well as your logical aptitude. Although fluency in English is necessary, the emphasis of the test is not on vocabulary or cultural knowledge, perhaps making this a good test for those who do use English as their primary language. An understanding of the fundamentals of algebra will prove helpful on this test.

Please do not use any reference materials (e.g. books, calculators, online or computer resources) or the help of anyone else in working these problems. You may use scrap paper, and pen or pencil.

Many of the problems are quite difficult, and several may contain words, names or terms that you are unfamiliar with. Be sure to answer every problem, even if this means guessing on some problems. There are no penalties for guessing.

Although there is no time limit, try to complete the test in 1 or 2 sessions.

Your estimated IQ score, general population percentile ranking, and the answers to the problems are all provided when you complete the test.
