I used this book to prepare me ... MENSA test! Although the types of questions are different, my choice was made for that book because of the quality of advice departing, the variety and the increasing difficulty of the tests, as well as the wealth of corrections. My goal has been managed - the book was a very good mind sharpening tool. It will be even more so a great way to preparation for candidates Tage Mage. My thanks to the authors.
