I don't put much value in IQ tests, because I don't think you can judge the whole of someone's intelligence just on that. To some degree they can be useful, else we wouldn't use them at all, but there are some really smart people with a low IQ, and some really dumb people with a higher IQ.
Regardless I'd like to try taking one again sometime, last I took it was in 10th grade. I feel like it's probably changed since then.
