British student Alex Chui has set a new record at the International Mathematical Olympiad (IMO), becoming the all-time most successful contestant. Last month, Chui, a year 13 student from Tonbridge School in Kent, achieved a perfect score in this year's event held in Shanghai.
This achievement earned him a gold medal, bringing his total IMO medal count to seven, with five of them being gold. The IMO, which has been running since 1959 and involves school-age contestants from over a hundred countries, has not seen any other participant win a medal seven years consecutively.
Chui's perfect score of 42/42 in this year's competition marks a personal best. He is due to study mathematics at Cambridge next term.
