Is 121 good enough on an IQ test to get into MENSA?

Answer 1

This question can not be answered. The answer depends on the test taken. The requirement is a score in the top 2% of the general population. This can mean 130 on test A, 132 on test B or 140 on test C. If you check with the Mensa office in your country and know which test you did, you can get the answer.

Another opinion:

What is said above is true. Where I live, you need 131+ IQ according to the Wechsler scale to get into Mensa. I do not know whether this applies internationally.
