A group of Korean high school students has won six gold medals to finish top for the first time at the 53rd International Mathematical Olympiad, which was held in Mar del Plata, Argentina, from July 4-16. The math competition drew over 500 high school students from 100 countries this year.

"The six-member Korean team garnered a total score of 209 points at the annual math competition to secure the top spot," the Ministry of Education, Science and Technology said on Monday.

Fifteen-year-old Kim Dong-ryul, the youngest Korean participant, scored 40 out of 42 to place second in the individual ranking.
