Gift & Humour

The Intelligence Quotient remains the definitive means of assessing brain capacity, and this classic book, originally published in 1962, was the first that permitted readers to determine their own I.Q. It includes an introduction by the prolific psychologist Hans Eysenck, followed by a range of easy to difficult I.Q. challenges. At the back of the book you can find the answers and your personal I.Q. rating.
