I would like to ask about music education at Sejong University.

Hello. I am from Naypyidaw. I will be going to Korea soon to study Music Production at Sejong University and would like to ask about the details. I don’t know what documents are required for admission. Some say that they are 정시, and some say 수시. What is the difference? I don’t know if people like me who don’t speak Korean can apply to the language school or if they can apply directly. I heard that the tuition and fees are high. I am also interested in whether these are true and what other scholarships I can apply for... I would be very grateful if you could explain what else I should do.
