You can download "Maximize Your Intelligence" from here FREE: www.personality-and-aptitude-career-tests.com/iqbook-utube.html It is result of my 12 years passionate self-study of psychometric like aptitude tests, personality tests and intelligence tests. When I launched my website, I had no intentions to study intelligence tests. But eventually, it became my main area of study and research. I am convinced that everyone is born with a level of intelligence which is highly influenced with diet, environment and education. However, you can't increase your intelligence too much. Yet you can maximize your intelligence to the limits unknown. When you take proper diet, do brain exercises and play brain games, you can maximize your intelligence. I am dedicating this channel for videos on intelligence and memory that I watched during my study.
