For a bit of fun, try the Mensa Workout...

This quiz is provided for entertainment purposes only; it is not an IQ test.  This score will not qualify you for Mensa.  The questions on the "Mensa Workout" are biased towards people whose primary language is English.  Mensa offers culture-fair testing throughout the world.  You have half an hour to answer 30 questions.  Answers to the questions and discussion of the answers are provided at the time you submit your answers.  While there is a 30-minute time limit to take the test, the amount of time you actually take in no way affects your final score.


The official Mensa mobile test is now available on iPhone and iPod touch.

Mensa Brain Test provides genuine Mensa questions of the variety used in official Mensa tests
