This page lists the authors and the proposing countries of the problems of the IMO. For many problems, the composers do not have the nationality of the proposing country. For instance, problem 2009/4 was proposed by Belgium, but only two of the three problem authors were Belgian, whereas the third is from South-Korea.

2024 IMO problems and solutions. The test will take place in July 2024 in Bath, United Kingdom. The first link contains the full set of test problems. The rest contain each individual problem and its solution.

2024年12月1日 · This page contains problems and solutions to the International Math Olympiad and several USA contests, and a few others. Check the AoPS contest index for even more problems and solutions, including most of the ones below. International Math Olympiad# IMO 1997 ; IMO 1998 ; IMO 1999 ; IMO 2000 ; IMO 2001

The IMO competition lasts two days. On each day students are given four and a half hours to solve three problems, for a total of six problems. The first problem is usually the easiest on each day and the last problem the hardest, though there have been many notable exceptions.

imomath is a website about math problem solving and math olympiads. The website contains problems, training materials, and information about the book The IMO Compendium that contains the solved shortlists from the International Mathematical Olympiads.

The IMO Compendium is a book that contains all problems ever given or shortlisted for the International Mathematical Olympiad (IMO) with solutions, and all of the available longlisted problems. The total number of problems exceeds 2000.

For example, in geometry problems I typically use directed angles without further comment, rather than awkwardly work around configuration issues. Similarly, sentences like “let R denote the set of real numbers” are typically omitted entirely. Corrections and …
