How ranking works

General scores run from 0 to 100 and are sorted from highest to lowest across all eligible learners before results are divided into pages of 100.

General score Balances accuracy and breadth. Both matter: one lucky answer remains low, while answering without any correct result gives zero practice score. Correct Most correct answers; ties use answered problems. Answered Most completed problems; ties use correct answers. Accuracy Highest correct-answer percentage; ties use correct, then answered. Official Highest supervised event score; ties use verified event count, then practice.

General score formula

Let n be Answered and c be Correct.

Accuracy A: A = 100 x c / n. Breadth B: B = min(100, n), so 100 answered problems establish full breadth.

Practice score P is their harmonic mean: P = 2AB / (A + B). If A = 0, then P = 0.

General score G: without an official result, G = P. With an official result O, G = 0.60P + 0.40O.

For example: 1/3 gives G = 5.5, 1/1 gives G = 2.0, and 0/3 gives G = 0.0. For comparison, 90/100 gives G = 94.7.

Online ranking assumes every student answers independently and honestly. It measures practice, not an official title. Scheduled offline Olympiads provide supervised verification.
