I just wanted to know. For foreigners, will some students discriminate or stereotype them as I see in some of the reviews. Is the transportation ok? How long exactly can it take to go to Seoul? Is it cheap to hang out outside? Is it near to an airport? Is there a special class for foreigners for those who doesn't speak Korean? I need to know this asap. If anyone knows, please answer my questions. Hope you have a nice day.
