the middle school students' test was introduced (JKMO, Junior Korean Mathematical Olympiad).
In the 53rd International Mathematical Olympiad (IMO), the Korean delegation won 209 out of 252 out of the total score and 6 gold medals and ranked the first place for the first time in history.
[1][2][full citation needed] From then, Korean mathematicians have made outstanding achievements in advanced math research and International Mathematical Olympiad.
[citation needed] About 12 to 13 students (twice the number of final candidates) are selected based on the grades obtained by multiplying the grades of five tests (KMO second test, Romanian Master of Mathematics, winter school mock test, APMO, and KMO final exam) by the weights set by the Korea Math Olympiad Committee.
IMO mock tests are conducted for these 12 students; based on their scores, six finalists will be selected by the Korea Mathematics Olympiad Committee.
