Meet the class
Most admissions stories follow the prodigies. This one follows everyone else. Our cohort is built around a typical well-resourced public high school — big, suburban, the kind that sends nearly all its graduates to college but only a handful to the Ivy League.
To make the contest realistic, the model surrounds that school with 24 peer schools just like it — matched on test scores, grades, and where their graduates actually enroll. Together they form a class of 1,200 seniors.
The applications are in. First up: the round where you bet everything on one school.
Early Decision: the binding bet
In November, some students sign a binding promise: admit me, and I'll come. No shopping offers, no comparing aid packages. It's the single biggest gamble in the process — trading away all your flexibility for a statistical edge.
And the edge is real. It grows as you move down the prestige ladder: a Top public / LAC admits early at a far higher rate than a Selective school — while the most selective tiers barely blink.
Most of the class is still waiting. The non-binding round comes next.
Early Action, and the art of waiting
Early Action is the non-binding cousin: you learn your fate in December but keep every option open. For the cohort's reach schools, it's mostly an exercise in patience.
At the very top — the HYPSM tier — the bar is almost all rejection, with a thin band of acceptances at the base and a sliver of deferrals: applicants pushed into the spring pool to wait a little longer.
The deferred join tens of thousands of unseen rivals. March will settle most of it.
Regular Decision: the main event
March arrives, and with it the deluge. Every seat not already claimed in Early Decision is now contested — and the cohort is no longer competing only against itself.
Side by side, the early and regular acceptance rates tell the whole strategy: at nearly every tier, applying early bought better odds than waiting for spring. That gap is exactly what the binding bet was paying for.
The envelopes are open. For the first time all year, the students hold the cards.
Decision Day
Now the power flips. Colleges have made their offers; students choose where to go. Yield — the share of admitted students who actually enroll — is the number that keeps deans of admission up at night.
The pattern is lopsided. When a dream school says yes, almost everyone says yes back. Further down the ladder, colleges admit two, three, even four students for every one who shows up in the fall.
But not everyone is settled — and the waitlist still has a few cards left to deal.
Where everyone landed
Here's the whole class at once — 1,200 squares, one per student, sorted by where they ended up. Color marks the tier they enrolled in; the squares at the bottom didn't win a seat at any of the 111 selective colleges the model tracks.
That last group matters. 324 students — about 27% of the cohort — were shut out of every modeled college. In real life they head to strong regional publics and community colleges this map doesn't draw. A "good public school" is no guarantee.
One question remains: should you believe any of this?
Does the model tell the truth?
A simulation is only worth as much as its grip on reality. So here's the test: for every college in the contest, we plot the rate the simulation produced against the real rate each school publishes in its Common Data Set.
Points hugging the diagonal are accurate. The cluster is tight where it counts — the personalized pipeline uses per-college calibration and pool-strength-aware thresholds, not a single one-size-fits-all national average.
