Extremely inaccurate

I would not recommend this app to anyone looking for an accurate iq. I have a score of 147 on the real iq test, but on this app I supposedly have an iq of 70 .the only reason I even downloaded this was for a contest between my friends and I. Not to mention if you look at the answer key many of the answers are incorrect.
