Intelligence is the general mental capability that involves the ability to reason, plan, solve problems, think abstractly, comprehend ideas and language, and learn.
This test is one of the most scientifically invalid intelligence tests currently available on the internet. It uses a collection of unrelated questions, some of which I found on the internet and some I invented myself, to rate your 'intelligence' (mainly in terms of logic, verbal reasoning, pattern recognition, mathematics and short term memory) and determine whether you are brainy or braindead.
There are 35 questions which you should attempt to answer as quickly as possible. If you don't know an answer then just skip the question. Don't use pen or paper, or a calculator, just your mental power (and your hand to move the mouse to enter answers.)
