Cogni44

Collection Of Guileful Numerical Items

Cogni44 is a high range pattern recognition test consisting of 44 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. If there is more than one question mark, it serves as a hint indicating how many digits should be placed there. The test is free of charge. To receive your score report, please send your solutions to dawid.skrzos@o2.pl along with proof of your identity. Please also send all of your prior scores on high range IQ tests. This will help me in normalizing the test. Three attempts are allowed, however, only the first two attempts are considered official scores.
