I need advice on applying to Hankuk University of Foreign Languages.

Hello. I am a final year English student in Mandalay. I want to continue my master's in international relations at 한국외국어대학국. I am currently looking at the admissions website and I see that there are various programs, tuition fees and registration fees for each program are different. I don't know how to get a scholarship opportunity. I want to choose a school, but I think the prices in Seoul are too high, so I am very disappointed... I would also like to know the difference between 편입 and regular admission (수시, 정시). I am also wondering what is the best option if I go to 어학당. Can you tell me how to prepare realistically for seniors?
