Numerus Classic


Numerus Classic is my step toward creating high quality IQ tests.

It consists of the best items from Numerus and Numerus Light,
based on my quality analysis from http://ivec.ultimaiq.net/quality.htm.
It provides great IQ measure in the interesting range from IQ=120 to IQ=190.
If you want to take the test, please send your solutions and previous IQ scores, following this fee schedule.
You can find the first norm report, here.

Two submissions are allowed on Numerus Classic for everyone.
Each testee has the option of requesting a converted score from their combined submissions of Numerus and Numerus Light.
Each converted score request counts as a submission on Numerus Classic.

If you think that some solutions are not unique, you can choose three items and send two solutions for each of them.
You must send detailed explanations for both solutions in that case. Enjoy the test!!!
