International Mathematics Olympiad 2007

In the 48th International Mathematics Olympiad (IMO) being held in Hanoi, Vietnam, the Russian delegation came in first with six gold medals and the Chinese won second with five golds and one silver. Vietnam and South Korea came tied for third place with South Korea with three gold and three silver medals.

Most teachers and students commented that the six questions given over the two days of the contest, July 25-26, were hard but interesting. And as in previous years, the third and sixth problems were more difficult than others in order to help identify outstanding contestants. The highest possible score for all six questions is 42. The top 1/12 of the contestants receive goal medals, the top 2/12 of the remaining, silver medals, and the next 3/12, bronze ones. Of the rest of the contestants, anyone who records the highest possible score (7) on any one question is awarded an honor prize.

IMO, an annual competition for mathematically gifted high school students from all over the world, is held in a different country every year. The first IMO was held in 1959 in Romania, with 7 countries participating. Spain and Germany will respectively organize upcoming IMOs in the next two years.

The highest score was 37 by Konstantin Matveev of Russia. Peter Scholze of Germany and Caili Shen of China scored 36. Danylo Radchenko of Ukraine and Pietro Vertechi of Italy scored 35. Last year Zhiyu Liu of China, Iurie Boreico of Moldova and Alexander Magazinov of Russia could get perfect score of 42 (for solving 6 problems).
