Are you a logical thinker? A numerical whiz? A verbal genius? Or are you visually inclined? Are you looking for intellectual stimulation? Find out how smart you are (and increase your IQ) with the Intelligence Test.

This IQ test measures several factors of intelligence, namely logical reasoning, math skills and general knowledge. It also measures your ability to classify things according to various attributes, and to see analogies and relations among concepts or things. It doesn't take into consideration verbal, social, or emotional intelligence.

This test is supposed to assess your intellectual potential, not your performance under stress. Therefore, there is no time limit. Nonetheless, this test is usually completed in less than one hour. You may use a calculator, a piece of paper and a pencil. Do not use software to solve the problems, even if you programmed it yourself. And, of course, unless you want to assess a team IQ, you will have to work alone. Before you start, make sure that you have about an hour of free time during which nobody will disturb you.

Read carefully every question and select your answer in the right column. In order to have the Classical Intelligence Test scored, you need to select an answer for every question. Some questions are designed to be very difficult. If you cannot figure out the answer, simply select I don't know and move on.
