Zhuo Qun Song (Chinese: 宋卓群; pinyin: Sòng Zhuōqún; born 1997), also called Alex Song, is a Chinese-born Canadian who is currently the most highly decorated International Mathematical Olympiad (IMO) contestant, with five gold medals and one bronze medal.




Early life


Song was born in Tianjin, China in 1997. He and his parents moved to Canada in 2002. Song was brought up in Waterloo, Ontario.
Song was interested in mathematics at a very young age where he started participating in competitions in first grade. By fourth grade, Song was participating in competitions such as the Canadian Open Mathematics Challenge and the American Mathematics Competitions. In fifth grade, Song became interested in solving Olympiad type questions and started training to solve them.
In 2011, Song moved to the United States to attend Phillips Exeter Academy.




International Mathematical Olympiad


In 2010, when Song was in the seventh grade, he represented Vincent Massey Secondary School in the Canadian Mathematical Olympiad where he finished first place.
In the same year, Song represented Canada in the 2010 IMO where he won a bronze medal. He would continue to represent Canada for 5 subsequent IMOs where he obtained a gold medal each time. He obtained a perfect score on his final run in 2015, the only contestant to do so that year. The performances made Song the most decorated contestant of all time. In 2015, Song was also one of the twelve top scorers of the United States of America Mathematical Olympiad, representing Phillips Exeter Academy.
