Research online options. Although anyone can make up an "IQ" test and put it on a website, some very legitimate resources are available that can walk you through an IQ testing process and provide you with your test scores almost immediately. Most online resources for intelligence quotient tests are free of charge.
Talk to your doctor if you have concerns that have led you to doubt your intelligence. Depending on your age, health or history of accidents or injuries, it is possible that a rapid decline in brain function could indicate a problem. Even if you are just curious about your intelligence quotient, your doctor may be able to refer you to a professional service who will conduct the IQ test and allow you to obtain your IQ test score in a personal, professional and discreet manner.
Try multiple tests. Many psychologists, universities, doctors and other experts in the field of mental health and education have different theories regarding intelligence factors. As a result, they each make slightly different, and sometimes very different, intelligence quotient tests. Bookstores also usually carry books that contain IQ tests and provide advice and information on how to improve your score. Obtain your score from each testing source, and develop your own conclusion. Keep in mind that intelligence measurement is based on human theories, not proven scientific conclusions. That said, discover your IQ test score and interpret it lightly, keeping in mind that there is a reason that most colleges and workplaces don't require a certain IQ to be hired to perform a job. Make the process of obtaining your IQ test score fun, not stressful.
