In recent college admissions cycles in South Korea, a surprisingly large share of students who earned spots at the prestigious SKY universities—Seoul National University, Korea University, and Yonsei University—have decided not to enroll even after receiving official acceptance. According to the most recent data from early decision results, approximately 33.7 % of all initially accepted SKY applicants chose to decline enrollment instead of starting classes, meaning that about one in three students did not matriculate to the schools where they were first admitted. 
When we look at each university individually during one recent admissions cycle, the percentages vary widely. At Seoul National University, only around 5.9 % of admitted students declined to register, while at Yonsei University a much higher 46.3 % chose to decline enrollment and at Korea University 46.6 % did the same. This means nearly half of the students offered spots at Yonsei and Korea University through early admissions opted out of enrolling. 
The pattern also appears in regular admissions data in the previous year’s general admissions cycle, 36.1 % of accepted SKY candidates did not register at these universities, meaning more than one-third of all admitted applicants chose not to take up their places. 
One major factor behind these high non-enrollment rates is that many students who are admitted to SKY universities, especially in science and engineering majors, also receive offers from expanded medical school programs or choose to pursue medicine directly instead. For example, in the early decision cycle noted above, nearly half of the natural science admittees at Yonsei and Korea University declined because they are believed to be moving into medical programs. 
This trend reflects broader shifts in student priorities. Rather than automatically enrolling in SKY universities because of their prestige, many students are now weighing career goals, major fit, medical school opportunities, international study options, and personal preferences. As a result, the traditional idea that getting into a SKY university almost guarantees enrollment is no longer as reliable as it once was, and the proportion of students declining acceptance continues to be significant year after year.
