Application Tips for International CS Students

What Admissions Committees Look For

Korean CS programs evaluate international applicants differently from domestic ones. Here is what matters:

1. Academic record: GPA is important, but the difficulty of your coursework matters more. A 3.5 in a rigorous curriculum impresses more than a 4.0 in an easy one.

2. Mathematics preparation: Strong performance in calculus, linear algebra, discrete math, and probability significantly strengthens your application.

3. Programming experience: Most programs expect applicants to have meaningful programming experience — not just coursework, but personal projects, competition results, or open-source contributions.

4. Research experience (for graduate programs): Publications or research assistant experience is expected for top PhD programs and strongly preferred for MS programs.

5. English proficiency: TOEFL 90+ or IELTS 6.5+ is typical for English-taught programs. Some programs require higher scores.

6. Statement of purpose: Korean universities want to see specific reasons for choosing their program — reference specific labs, professors, or curriculum features.
