“Mull-Suneung(Water level-College Entrance Exam in English)” or “Bull-Suneung(Fire level-College Entrance Exam in English)” is a well-known phrase when describing the difficulty of College Entrance Exams in Korea. Concerns over the so-called "Mull-Suneung", which means exams that are too easy, have grown as the government announced that the Ministry of Education will not set "Killer Problems" or the highest-level questions from the 2024 CSAT. In announcing measures to reduce private education, the Minister of Education said, "It is not fair to set questions not covered within public education," and declared, "We will exclude all killer questions based on the outside of the curriculum." In response, the majority of students and education experts expressed concerns that while the policy could reduce private education by not asking high-level questions that cause excessive private education, it would result in lower difficulty in the test. As the test becomes too easy, the top students will suffer from the lack of chance to prove their superiorities. Famous Internet lecture instructors and teachers at large academies did not stay still, too. The majority of instructors and education experts said that such a big change in the upcoming college entrance exam will confuse students in preparing for the test. High school teachers also called for ways to distinguish the top students, fearing that the number of perfect scores would increase and the first place of the test would disappear. 

 Ultimately, the only way to solve this problem seems to be to ask the most difficult questions within the limit that does not deviate from the curriculum. It is true that education overheating and private education in Korea are at a serious level. It is important to reduce private education and allow students to show their true skills in exams, but more discussion is needed on whether it is best to abolish difficult questions in the college entrance exams.
