The European Girls’ Mathematical Olympiad is an international mathematics competition similar in style to the International Mathematical Olympiad, with two papers taken on consecutive days. Participating countries send teams consisting of four female mathematicians of school age. The first EGMO was held in Cambridge, United Kingdom in April 2012.
The problems and solutions of the previous years are also available at the official page, under “Past and Future EGMOs”. For example, for EGMO 2020, the problems (in many languages) and the solutions (in English) can be found here.
