Do I need to know Korean to study a master's at KAIST or Yonsei University?

Generally no, you do not need Korean for a master's at KAIST and Yonsei, as most programmes run in English, though some Yonsei programmes require Korean. KAIST's IELTS minimum is 6.5, and thresholds vary by department, typically IELTS 5.5 to 6.5 or TOEFL 71 to 90.

Generally no, you do not need to speak Korean for master's programmes at top universities such as KAIST and Yonsei. They run mostly in English, so TOPIK is usually not compulsory, though some Yonsei programmes require Korean. You will need an English test score instead.

Learning Korean anyway

  • Korean lessons are still offered on campus if you want to pick up the language.
  • Master's admission also needs a bachelor's degree.

My Advice

Focus your effort on your English test score and your programme fit. Picking up some Korean once you are on campus can make daily life easier, but it is optional. Confirm the exact score on your programme's official page.
