IQ Tests are the standard tests designed to measure your intelligence. While you cannot actually improve your intelligence, regular testing will enable you to increase your powers of vocabulary, calculation and logical reasoning. This new book includes 10 completely new tests, of 40 questions each. At the end of each test there is a guide to assessing your performance, and also a cumulative score for performance on all 10 tests. Each test has a time limit of 90 minutes. Use the questions to challenge your mind, build confidence in your mental abilities, and improve your chances of being successful on similar IQ tests. Use this and other books in the IQ Workout Series as a fun and informative way of testing, assessing, and expanding your brainpower! These books are suitable for anyone from 18 to 80 who wants to put themselves to the test. Ken Russell and Philip Carter have written nearly 100 books on all aspects of testing, puzzles and crosswords. Read Less
