# China Girls' Mathematical Olympiad

The China Girls' Mathematical Olympiad (CGMO) is a math competition with a proof-based format similar to the International Mathematical Olympiad. The competition is organized by the Chinese Mathematical Society. Owing to the fact that girls are outnumbered by boys in mathematical competitions, this competition was created specifically for girls. The aim of the CGMO is to encourage more girls to study mathematics and to foster friendship. It was originally organized in 2002 for teams of girls representing different regions within China. The Chinese organizers decided to invite other nations to send teams of girls from their countries. The Philippines has participated since the first edition. Russia has participated at least since 2004. The United States participated in 2007–2012. Singapore has also participated.
The CGMO is held in mid-August and is hosted by a high school every year. Apart from the mathematical competition, girls also have a chance to learn aerobics and perform on stage.
The CGMO has inspired the creation of the European Girls' Mathematical Olympiad.

## Format

Each team consists of four high school female students. The competition is held on two consecutive mornings from 8:00 to 12:00. The contestants solve 4 problems on each day and each problem is worth 15 points.

## Awards

There are gold, silver and bronze prizes for individual contestants and a best team award.
Around 15 highest scoring girls are qualified to participate in the Chinese Mathematical Olympiad.
