Cogni22

Cogni22 is a high range pattern recognition test consisting of 22 numerical items that should be solved in the most logical and simplest way. There is no time limit, and answers should be carefully thought out. Discussion with others about solutions is not allowed. The items are not arranged in order of difficulty. To receive your score report, please send your solutions to dawid.skrzos@o2.pl. There is a fee of 10 EUR for scoring each submission, which you can pay via PayPal to dawid.skrzos@o2.pl (choose the option to send to a friend or family) or directly to my bank account (Dawid Skrzos, IBAN: PL93156000132016122130000003, SWIFT/BIC: GBGCPLPKXXX). Three attempts are allowed, however, only the first two attempts are considered official scores.
