SAT scores and IQ were correlated with socioeconomic status even before there was an essay section on the SAT. Dude.
Yes. And now there's an essay section, so the correlation between IQ and SAT score is broken. It goes deeper than that, though:

The researchers calculated how much of the variation in MCAS scores was due to the school that students attended. For MCAS scores in English, schools accounted for 24 percent of the variation, and they accounted for 34 percent of the math MCAS variation.
However, the schools accounted for very little of the variation in fluid cognitive skills — less than 3 percent for all three skills combined.
The correlation between SES and SAT score remains strong, because teaching to the test and extensive test coaching work, and those are things you can buy, even though they don't make you any smarter.
