IQ Booster: Improve Your IQ Performance Dramatically

Well, well, let me see, hmm. It was a good book in that it increased my IQ by about 15 points. And I advice anybody that is about to take an IQ test in school, to read this book before taking. As the person who commented above, lots of space are not used, and much of the book were tests, rather than techniques taught. I also have another problem with this book. The author emphasizes how unbiased he liked his tests to be. But it seemed as though his vocab section was kinda culture-bias. Most of my errors were in the vocab section, and this resulted in the decreasing of my IQ score by about a 15 pt difference from my IQ results in school. Thus, in total, the book didn't increase my IQ. However, it was fun while doing it! Anybody who's anybody should read this book.
