For a while I was using something called 'R' with various ethnicity calculators . It didn't require me to be 'Brain of Britain', as I saved the commands- and pasted them into R as required.
When it comes to anything that's useful in real life I'm near, at, the back of the class. High range IQ tests on the other hand, which serve no useful purpose, I'm quite good at those. I think ,or at least I've read articles saying so, that that lack of practical intelligence is a very schizophrenia related thing.
