There are plenty of real IQ tests on the net (try a quick
google search). But they're not quite as reliable as a 'real one' conducted under exam conditions (though a lot cheaper, and not bad!) - you have to be quite honest with the timings, plus half of them are only valid in the range, say, 70-130 and have real problems if your IQ is higher (I say
higher because you're on TFP and I think <70 is a bit unlikely
)
