Mississippi has the best demographic-adjusted NAEP (4th & 8th grade) scores now

The "Mississippi Miracle" started in 2012 when the Republican governor/legislature introduced phonics-based instruction and began to hold back ~10% of 3rd graders per year who fail a reading test Image
In contrast, Oregon, with the lowest demographic-adjusted scores, has a Board of Education that has indefinitely "paused" since 2020 the use of any standardized test as a graduation requirement

Most of this stuff isn't rocket science

Bertrand Russell's parents died by the time he was 4 and in 1876 he went to live with his grandfather, the last Whig prime minister, who as a young man had met Napoleon at Elba

In 1966 at the age of 94 he met Paul McCartney and converted him to his anti-war stance on Vietnam
Winston Churchill (1874–1965) rode in Britain's last great cavalry charge (Omdurman 1898) and later in life ordered Britain's first hydrogen-bomb program

W.E.B. DuBois (1868–1963) was born three years after the Civil War and died the night before the March on Washington

The narrative in which college admissions is inherently a rat race even without DEI/legacy-admissions/etc doesn't pass napkin math

1) 3.8m students graduate hs each year
2) Top-20 colleges admit ~40k total

So they could just admit a large majority if not all 1550+ SAT scorers?
In 2023, of the 2.13m students who took the SAT, only 38k scored above a 1500 and only 8k scored above 1550

So they're not a dime a dozen; it's just that every single university chooses the majority of their class from students who score below 1560

Caltech (score-oriented by reputation) still has a median score under 1560

About 1% of high school graduates attend a top-20 university (Ivies, MIT, Stanford, Caltech, Duke, Johns Hopkins, UChicago, Cal, UCLA, Georgetown, whatever)

So it doesn't have to be 𝑡ℎ𝑎𝑡 competitive

I often hear people say they increase their efficiency/impact by trading time for money, e.g. valuing their time at $35/hr and booking an Uber for $15 to save 30 minutes of walking as a result

But is this compatible with your marginal time value in most models of productivity?
Extreme example: suppose that you can only work productively for 6 hours a day, then your time is worth $0 afterward and you should just walk

I guess under other simple models, non-Uber examples like administrative tasks exhaust some kind of motivational resource ineffectively
Maybe a simple model involves an "energy level" that goes up at "rest"

Then "tasks" all have "utility" and "energy cost"

This justifies spending money specifically on tasks which exhaust energy inefficiently when that energy would have been better used otherwise

Or something
