Natplus — Contest

By J. S. Moreau

This is the "Plus." Only the top 10% from Day Two advance. They enter a sealed room. No phones. No watches. Each student is given a single problem, but it is incomplete. Halfway through the three-hour session, a proctor reads aloud a "Variable Update"—new data that fundamentally changes the problem. In 2019, the Variable was: "Ignore the first two pages. Assume pi = 3.2." In 2021, it was a live video feed of a stock market ticker that students had to incorporate into a calculus proof. natplus contest

One thing is certain: 400 brilliant, terrified, sleep-deprived students will walk into that hall. They will sit in perfect silence. They will face the Variable. They enter a sealed room

"Standardized exams are rearview mirrors," Voss famously said in her manifesto, The Plus Condition . "They tell you where a student has been. NatPlus is a headlight. It shows you where they could go." Each student is given a single problem, but it is incomplete

On a rain-slicked Tuesday evening in a nondescript convention hall outside Chicago, three hundred teenagers sit in perfect silence. The only sounds are the scratch of pencils, the hum of industrial HVAC units, and the occasional, stifled sob. A timer on the wall ticks down from 180 minutes.

One finalist from 2020 (who asked to remain anonymous) told me: "I trained for eighteen months. I solved over two thousand practice problems. Nothing prepared me for the moment they said, 'The square is now a triangle. You have ninety minutes.' I laughed. Then I cried. Then I solved it. Barely." Every enduring contest has its myth, and NatPlus has the Dark Packet .

In 2015, a printing error occurred. The Day Two booklets for Section B (seats 112–145) contained a completely different set of problems—problems that, by all accounts, were impossible. One question allegedly asked: "Prove or disprove the existence of a finite number that is its own successor, using only the axioms of Zermelo-Fraenkel set theory and a haiku about entropy."
