Accurate?

I got an IQ of 146, which is genius. I am 13 and have taken many other IQ tests. I have gotten around 120 to 130, or even lower. I think that this app is fun, but I got 11 answers wrong and 19 right, which is like 70 percent correct. How does that qualify me for genius. At least it did not crash though. Great for a free app, but horrible if you are trying to get an accurate idea of your IQ.
