If it's a test taken online, it is almost certainly far from accurate. A true IQ test will be administered over the course of hours and have multiple phases of "questions" involved. I have an IQ of 146, last checked when I was 14 years old. I am now 23 and intend to take another again in due time. My friends often walk up to me and inform me that they just took an IQ test and found they have an IQ of 185, for example. I know my friends and inform them that their results are profoundly wrong. Upon inquiry as to where they took the test, they tell me online. Upon inquiry of how long the test took, they tell me five minutes. I only have one friend whom I know to have an IQ greater than mine, and it is by far greater.
Regardless, IQ does not define skill and barely defines intelligence. I may have an IQ of 146 (give or take), but I am still prone to stupid mistakes. There are many different types of intelligence. I view IQ as nothing more than a number that demonstrates the simplicity of being successful in your endeavors. Those with lower IQs are not devoid of that ability, but simply must put more into their hard work and tenacity skill sets. Someone with an IQ of over 200 that has no tenacity or drive to accomplish anything, will not accomplish anything. Nothing comes from nothing.
That said, I am off to browse this site in an effort to find this test to make a diagnosis of its accuracy.
