Not everyone can afford to sink time into learning SAT tricks.

No, but I think the point is a combination of Chesterton fence and Goodhart's law. The personal statments and the like, by becoming the primary targets, will cease to measure achivement, and instead measure wealth. So instead of changing without a plan, make a plan to replace SAT2 with something less subject to wealth

MIT is removing a test which rewards the wealthy and punishes the poor. That's good. But the other metrics that MIT currently use are more punishing to the poor, and more rewarding to the wealthy.

With the removal of this element, MIT is left relying on personal statements, recommendations, and the like. With those metrics as the targets, the kids of the wealthy will fund their child's various activities for the sake of giving them a better application.

I find this truly baffling. How can it be considered good use of time for someone to sink endless hours of time into learning the ins and outs of some stupid test that is not useful for anything? Just think about the man years of enthusiasm and creativity wasted on learning to score on a test, instead of something truly useful.

I understand why the students do it, I don't understand why anyone would consider it a good system.

There are plenty of kids in the US who can't afford to bring lunch to school, let alone pay $20 for a SAT prep book. Many of these kids don't have a computer or Internet access at home for that matter, so Khan Academy isn't much good to them either. When we talk about rich vs poor kids, there's a HUGE gap that many people don't realize.

Anecdote: When I was younger, I used to take a public bus to a local bookstore and work through the SAT practice books (on separate scrap paper of course).

It sounds like you didn't have to pick up younger siblings at school when you were younger. That's the reality for a lot of poor kids. Raised by a single parent, the older siblings are in charge of looking after the younger ones. The parent often does not get home from work until late (and may have multiple jobs).

I did actually. I was the oldest of three.

I'm not saying the poor aren't disadvantaged. It's just that the disadvantages are more along the lines of attitudes towards education in the first place (along with everything else). There are also fewer people nearby that serve as an "example" on how to learn or get ahead.

I don’t think that gap is huge in terms of internet access - there’s certainly a gap but it’s mostly a function of parents limiting access in my experience.

84% of teens have smartphones in the US. A large percentage of that remaining 16% have access to internet at school, as 98% of schools have broadband internet.

They have public libraries with both computers and books. Access has never been the issue if there is the will.
