As a visual learner, I was looking forward to testing my Visual IQ.
I did very well (119, the max is 140), even though I started making educated guesses about halfway through and making outright stabs in the dark for the last 10 (of 39 questions). The test allows 40 minutes, so sharpen your frontal lobe, and good luck!
The bad news is, the whole site is in a foreign language (Anyone know what nation is ".dk"? Denmark?) so the analysis of your results will be tough to interpret!
