Ranging from the challenging to the downright diabolical, these IQ tests from the puzzle editors of Mensa Magazine stretch brainpower to the limits of its endurance. That’s why they’re so effective at adding vital points to your IQ score. All it takes is a little tenacity and practice to work through these hundreds of questions, which assess verbal and mathematical skills, plus general knowledge and logic. Several “culture free” examples use diagrammatic problems rather than language, thus overcoming any linguistic barriers. The different types of questions include classifications (where you find the odd one out in a word list or group of figures); synonyms and antonyms; analogies; visual matrixes; and sequences. A scoring chart and answers are included.
