Korean universities have no scores. Are all conditions for students as a whole. If you want to go to Seoul National University, you must have at least 5 points in Korean, or 6 points in IELTS and 70 points in TOEFL. Language is important. If you want to go to graduate school, you must first be an undergraduate who graduated from the national "2 1 1 engineering" university. And the graduation time is not more than two years before you are eligible to apply.
