Not a culturally fair IQ test
Questions are loaded so that people with a classical education are ranked high. A question like "if you using a 52 card pack of cards and pick an ace, what are you chances of picking another ace". Answers given: 1/13; 1/169; 1/225; and another one I cant quite remember - clearly the answer is 1/13 (or close to) because there is a presupposition that the deck has been reset without the first ace; but you could read into it that this is an overall chance; the question wording can be confusing if you are not careful. Also, their grammar questions are unusually hard using synonyms or words that may be related through a thesaurus as their answer choices. Only one is definitively right while the rest are close in meaning. Again, only classical intelligence is being tested here.
STAY CLEAR OF THIS APP as it is not a culturally fair IQ test.
