As an exchange student it was a little difficult for me, at least at the beginning, to comunicate and find locations inside the Campus. The majority of the staff (unless they were in the International office) did not speak English, so you need to fond korean classmates/friends that will help you with that (they are really nice!).
Out of that I really liked the classes taken there. Unfortunately, my classes where not given by any korean proffesor; only foreign ones. But sitll I really liked them. The knowledge is wide and it becomes easy in participating at sessions. Besides, the self-studing method becomes the best tool to improve your knowledge and have good grades!There are also a lot of team work which gives the result of many opinions and points of view that are fun to work with.
All of the classes where given in the new buliding and that was really good. But all the rest of the buildings had an old infraestructure. Maybe they could invest and upgrade those buildings.
The location of the Seoul Campus is really good because it is near the subway and if the cafeteria food does not suit for you, you will have a lot of options around it.
In general I really liked my experience at Hankuk University of Foreign Studies.
