Virtual IMO 2021 – Russia
On July 18 2021, the opening ceremony marked the beginning of the 62nd International Mathematical Olympiad hosted by St. Petersburg. As in 2020, the global travel restrictions due to Covid meant the event was held in an online format. The team of each country gathered, where possible, in a single location to attempt the papers with light remote invigilation. A total of 619 schoolchildren representing 107 countries took part, with the Chinese team coming out on top.
