Intelligence has been defined as a ‘mental capability that, among other things, involves the ability to reason, plan, solve problems, think abstractly, comprehend complex ideas, learn quickly and learn from experience. It is not merely book learning, a narrow academic skill, or test-taking smarts. Rather, it reflects a broader and deeper capability for comprehending our surroundings.’

Mensa, an invitation-only international high-IQ society, is only open to people who score at the 98th percentile or higher on an approved intelligence test. Members range in age from 2 to 102, and include engineers, homemakers, teachers, actors, athletes, students and CEOs. They share only one trait — high intelligence, in the top 2 percent of the population. 

The organization offers this mini-quiz to test your brain, so take the test to see if you’re Mensa material. Good luck! (answers are at the bottom of the page)
