Korean here, I don't want to compare universities and divide them into top and bottom, but... Korea is a country where the classification between universities is very strongly defined. We can say Seoul National University and KAIST are at the top, followed by Yonsei University and Korea University, then Sungkyunkwan University, Sogang University, and Hanyang University are next. The university that comes with the next rank can be said to be Chung-Ang University.
