Used book Boost your IQ, C. de Sereville

Today, IQ tests have entered the realm of games; they are considered a fun challenge, a “mental workout” rather than a true judgment. Moreover, it is possible to improve one’s understanding of the mechanisms and logic behind the questions, ultimately leading to faster and more accurate answers! After a level test, this book presents 200 questions divided into five test categories: classic and visual tests, logic and matrix tests, verbal comprehension tests, decoding tests, memory tests. At the end of the book, a “grand test” of 47 questions allows you to check your progress.
