Scam
99% of advertisements on Facebook are a scam. Just like this one too. It was never advertised for a paid test, but at the end you get nothing if you don't pay. Not even a score. Other scammy IQ tests have at least the courtesy to let you pay only for the "extensive analytics". Online IQ tests are mostly for you feeling good. Nobody will tell you that you are stupid. Surely not when you paid for it. If you want a real IQ test, go to your local Mensa website (like mensa.org) which will probably have a free test developed by Mensa for orientation and then a real (paid) test which you can really believe and put on your wall. This test said that I finished the test in 8 minutes and 37 seconds which was faster than 97% of the people and I had a 99% success in "pattern recognition" whatever that means.
