As a 14-year-old I got 148 on one of these things, putting me at about 170 once the age is taken into account. However, all this proves is that I am good at taking IQ tests. Not that I'm "intelligent" (since no-one can really agree on what that is, anyway), just that I am good at taking that particular test.

To get your 'boosted' score (if you're under 16) multiply your 'raw' score by 16/[your age].
