No, neither IELTS nor TOEFL is required for eligibility to study MBA at Seoul National University (SNU) if you are an English speaker from a native English speaking country.SNU requires proof of English proficiency for international students whose first language is not English.
They accept scores from TOEFL iBT (80 or above), TEPS (551 or above), or a minimum Level 4 on the SNU Korean Language Center (KLEC) proficiency test.

SNU's MBA program does not require the GMAT or GRE for admission.
They have their own entrance exam for MBA applicants. This exam typically assesses quantitative and analytical skills, writing abilities, and English proficiency (for non-native English speakers).

In some cases, SNU might consider Graduate Record Examinations (GRE) or Graduate Management Admission Test (GMAT) scores in place of their own entrance exam, but this is not mandatory.
