Pretty decent

This test is very good in terms of similarity to what it purports to be: a culture fair test. Ive actually taken the Cattell Culture Fair (though I never did get my score from that one), and some of the questions here are exactly like what youd find on the Cattell, including the dot-location task.

What Im not so sure of is the accuracy of the score, which might be a little inflated. For example, I received a 146 on this test, but only a 128 (SD = 16) on the Otis-Lennon School Abilities Test, a 132 ( SD = 16) on Mensas formal admission test (Mensa no longer provides IQ scores, but I met the bare minimum to qualify, so this would be an accurate translation of the score), and a 36/50 on the Wonderlic Personnel Test, which roughly translates into a score of 132 on a scale with a standard deviation of 16. So my "real" IQ is probably in the high 120s, low 130s based on more proven tests, yet much higher on this one. That causes me to question the scoring accuracy.
