Based on the Raven Progressive Matrices format, this 39 question test can be completed in under 45 minutes and spits out a nice, neat score. I wish you could review your results in more depth, however, that would defeat the integrity of the score (because you could study and retake the test). Of course the best way to get an accurate measurement of IQ is through a test administered by a psychologist, but this app is free and the questions are legit. Give it a shot! Because it's nonverbal, you can give it to your kids as well and see how they do.
