> One thing I didn't know initially is that IQ tests are normalized so the mean is 100 and the standard deviation is 10.
No, the standard deviation is 15 IQ points, not 10. 130 puts you in the top 2%. I know this because my kid scored in the < 0.02%.
On the other hand, IQ tests are highly correlated to how much you prepare for them, which is why rich families score higher. There was a tutor on Reddit for private schools admissions who said she had never had a student who didn’t surpass the entrance qualifications for a standardized test. It’s very easily gameable.
