The Mensa IQ Test

M-E-N-S-A is an association that measures IQs. You will probably score between 70 and 130 on this IQ test because that represents 95% of the population. Did you know that William James Sidis has the highest IQ in the world? It's somewhere between 250 and 300. That's higher than Stephen Hawking. And he was mitted into Harvard University at 11 years old. A clever guy, very smart. But there are some extreme examples of people exceeding 130.
