This test does not measure intelligence, your fluency with words, creativity or mathematical ability.
It will however, give you some gauge of your mental flexibility. In the three years since the test was developed, few people have been found who could solve more than half the questions on the first try. Many, however, reported getting answers long after the testing has been set aside, particularly at unexpected moments when their minds were relaxed. Some reported solving all the questions over a period of several days. Take the test as your personal challenge. Sixteen correct answers out of the 27 in your first try means that you are some kind of genius.
