Practice makes perfect. No matter who you are, and irrespective of your age or educational background, you can always get to an impressive degree of proficiency in any skill if you put in thousands of hours of hard work. This book will prove this old adage for tests of human intelligence; you will yourself be surprised at how sharp it makes you, mentally. It functions both as a manual of instruction and a tool for brain recreation. It starts off with a quick look at some lateral thinking questions and then evolves to show you the most common mathematical and verbal question types that most people get wrong in the heat of the moment. I am also keen that you introduce a time dimension to your enjoyment of this book. In real life, we need to employ our intelligence so that it gives us answers in real-time. This means that, once you fix your time of comfort to correctly solve an IQ question in a given format, you should keep reducing that time of comfort, even if by a very small amount. After all, raising the difficulty level is how geniuses are made! I have provided answers and solutions to every single question in this book. I am sure that you will have a great experience!
