IQ tests don't measure shit. And for the most part are pretty easy. There are only so many "follow the pattern" drawings the test makers can come up with. And outside field specific nomenclature, English isn't getting a whole ton of extra words as time goes on. I've taken two formal ones at two different times in my life (child for school and then as an adult for an interview with a HFT company). And scored in the top 2-3 percentile. Is my score von Neumann levels of smart? Nah, not even close.
