Is 190 million KRW enough to put myself through 2 years of Korean language course plus 2 years of GSIS (Graduate School of International Studies) at Yonsei University?

190 million KRW is a generous budget and should be sufficient for most students, though the actual amount you spend depends heavily on your lifestyle and accommodation choices.

For tuition, the Yonsei Korean Language Institute runs about 1.5 to 1.8 million KRW per 10-week semester, so two years comes to roughly 12 to 15 million KRW. Yonsei GSIS tuition is around 6 to 7 million KRW per semester, making two years approximately 24 to 28 million KRW. Combined, expect to pay somewhere in the range of 36 to 43 million KRW for all four years of study.

For living expenses, a studio or one-room apartment near Sinchon where Yonsei is located typically runs 500,000 to 900,000 KRW per month including utilities, depending on the arrangement. Food, transportation, phone, and daily costs realistically add another 600,000 to 1,000,000 KRW per month for a student living modestly. Over four years that puts total living expenses somewhere between 55 and 90 million KRW.

Adding tuition and living costs together, your total estimated spend is likely in the 90 to 130 million KRW range, which leaves you a comfortable cushion from your 190 million. As long as you are not spending heavily on travel or extras, you should be financially comfortable throughout your studies.
