My IQ Science test is an open source IQ Test created by the University of Amsterdam and distributed for free via NeuroTask Scripting. You can also download the items and use them for any purpose, personal or commercial. Or you can simply take the test online here!
My IQ Science test is open source and MIT licensed. This means you can use it for any project - even commercial projects! Download it, customize it, and publish your own version!
The My IQ Science test is still very much under development and has ambitious goals.
Eventually, we want a test with a zillion items, a huge age range and IQ range, dynamic item selection, and great test-retest properties.
