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 .
Welcome to the most relentless, beautiful, and brutal academic contest you have never heard of. The NatPlus Contest was founded in 2008 by Dr. Helena Voss, a cognitive psychologist and former International Math Olympiad gold medalist. Her frustration was simple: existing contests, she argued, measured retrieval speed and narrow expertise. They rewarded the student who had memorized the most, not the one who could think the deepest. natplus contest
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. One finalist from 2020 (who asked to remain

A four-hour, 100-question multiple-choice exam. Sounds easy? The twist: each question has between 3 and 10 correct answers. Partial credit is a myth. You either circle the exact combination of letters—A, C, E, G—or you get zero. One former finalist, Priya Chandrasekhar (2022), describes it as "taking a Scantron test while someone randomly changes the locks on the answer key."
