There is no requirement for high school students to get excellent grades when applying for a language school. Whether you can apply for an undergraduate course after graduation from a CET-4 language school depends on your actual Korean level and whether the preparation of materials meets the different designated requirements of each school. In Seoul, the better language schools are Xijiang University, Korea University and Central University. Tuition fees in Dongguo, Sejong and Seoul are cheaper.
The undergraduate course starts in March and September every year, and the application is six months in advance. The Language Institute starts in four phases each year: March, June, September, June and 65438+February (Korea University and Hanwai University start in June, April, July and June, 10), so it is enough to prepare materials and submit applications 1-2 months in advance.
