Why are people so hung up on knowing what their IQ is? It's just a number, it doesn't measure your worth as a human, or your capacity to succeed in life, just your ability to correctly complete a certain set of tasks. Sure there may be some merits to having a high IQ, but to me the only measurable one is your own smug sense of self-satisfaction that arises from feeling like you're better than everyone else. I know people with high IQs, people who've gotten perfect scores on their SATs, people who are technically brilliant, but whose only fate in life is to be a stepping stone for an "inferior" person with more initiative.
Also, for the record I have no idea what my IQ is. The only tests I've taken designed to measure IQ have been for shits-and-giggles on less than reputable websites. It could be 155, it could be 55, I don't give a shit.
