A large portion of the SAT is knowledge of English vocabulary which obviously has nothing to do with IQ.

The mathematics questions nearly all use the same basic rules and are presented in the same format, and can easily be learned and trained.

SAT prep courses are ubiquitous and expensive because they work. Do people without training do well? Sure. Do people with training still do poorly? Sure. But a good SAT question would be "does this mean that training doesn't help or that there isn't a correlation between training and success?" because the obvious answer is no.

Vocabulary is a component of IQ.

>The many different kinds of IQ tests include a wide variety of item content. Some test items are visual, while many are verbal. Test items vary from being based on abstract-reasoning problems to concentrating on arithmetic, vocabulary, or general knowledge.

That's odd, when I learned about it a long time ago I was told it was intended to measure "inherent" intelligence, not the level of exposure/memorization of a massive set of (likely trivial) data points.

Vocabulary very clearly belongs on an achievement test, not an aptitude test (as I imagined IQ to be).

The prep is for turning a 1250 into a 1400 or so which basically determines if you get into Stanford or not.
