01.10.: Intelligence Day

October 1st, the day Mensa was founded in 1946, is International Intelligence Day.

On Intelligence Day, our IQ test will be administered simultaneously in about 100 cities all over the world. Take the chance to find out your IQ score, learn more about intelligence and meet Mensa. And, of course, join us after you passed the test!

In Switzerland, we are planning tests in Fribourg, Olten, Zug and Zürich.

For tests on Intelligence Day, we have a special 2 for 1 offer. Bring a friend to our IQ test, and he or she can take the test for free. For details, please see the test descriptions.
