I'd say that IQ tests are generally flawed. Of course, they might give you some idea of intelligence, though. But historically, they were used to draw line between intelligence with race, gender, or social class. Remember that human intelligence is complex and made up of many different components. Do some research, I think this topic is really interesting!

I took the IQ test back when I was 8, and got put into the Gifted Program. They told me that only 2% of people were as smart as me. The difference in percentage sort of makes me question what else I was told that might have been incorrect. We were sort of separated in Elementry school, but now in high school I have no clue if the rest of my friends are Gifted. I can't really tell either, everyone else seems to be just as smart if they try hard and focus on their work. 

Of course, this doesn't mean that you aren't really smart, just take the results with a grain of salt! Try to see who made the IQ test and if the methods used are generally accepted by psychologists. Look into the background of the test and the methods used.
