I spent an exchange semester in Korea University, in Seoul. Location for the University was good, it was about 20 minutes to the real city center.
My accomodation was in the University dormitory. This was really cheap way to live, but quality of the room wasn’t so good.
If you are planning to go to study in Korea, I recommend you to read the dormitory rules really carefully. Most of the dormitories here have curfew (Time when you are supposed to come back to the dormitory, usually before 1AM). Korea University didn’t have this kind of rule.
This was the cheapest dormitory available, I didn’t want it, but they chose to place me in there.
Studying in Korea University was pleasant, busy and hard at the same time. Most of the courses were harder than back in Finland, but with effort you can manage to get good grades out of them. So this made up a problem that there was no time to just sit down and relax, basicly I was studying or going out for attractions or dinners all the time.
The city itself is really big to explore, and you can find yourself at a new place at any time you wish! I visited Nami-island, Busan, Osaka and DMZ apart from Soul while I was doing my exchange studies. Nightlife is really great in Seoul, when you have got enough of seeing the traditional things!
I would recommend this University for exchange studies. There is alot to experience and normally the quality of teaching is good. Just remember to make sure you spend proper amount of time to view the courses, and don’t rely on that you can change them!
