Being in the KSN preparation team of my high school, there's always the talk about certain schools that constantly produce medal-winning students and stay as the powerhouse in the competition. There's also the fact that only 3 provinces have held the overall winner in all KSN series. Through this project I wanted to show the distribution of KSN medalist based on several categories from every series. Unfortunately, due to the lack of official documentation available in public I need to build my own dataset from various source with various format. Even worse is there's no official record about the first 5 years of KSN and many missing medalist info for 2006 and 2007 series. Therefore, only series between 2008 and 2021 are processed and analyzed in this project.
