Numerus

Numerus is high range IQ test. The most accurate IQ scores are expected in range between two and five standard deviations above average.
If you want to take the test, please send your solutions and previous IQ scores, with fee enclosed, to:

Ivan Ivec
Vlade Gotovca 13
10090 Zagreb
Croatia

You can send your solutions also by e-mail. You will receive raw score reports for your first and second submission as soon as possible. Approximated IQ scores will be updated once a year. You can find preliminary norm, based only on my experience, here.

Numerus is looking for the most complete and among them the most simple solutions.
I recommend to spend at least 20-30 hours solving the test if you want to achieve your maximum. If you think that some solutions are not unique, you can choose three items and send two solutions for each of them. But you must send detailed explanations for both solutions in that case. Enjoy the test!!!
