Did the classic IQ test on http://uk.tickle.com/test/iq.html

Your IQ score is 135!
Like a meticulous collector, you’ve fed your brain a unique set of facts and figures over the years and this makes you a facts curator.

The words in your head could almost fill a dictionary, and you’re equally adept at manipulating numbers and detecting important patterns in number sequences.

Sounds impressive: whatever it means.
