As we all know studying is like a culture in Korea. In my university there are a lot of smart and talented students. The education in KAIST is on high level and our professors are professionals in their fields. Actually, the education part is the important strength of my university. However, I do not think that it is the only thing you need for your happy college life. I think it is better to know Korean language when you came to Korea to study. In KAIST, almost all class in English, but sometimes you really need Korean. The noticeable weakness of KAIST is related to social life. It is not only because of my university, Koreans overall are very shy. Without proficient Korean language you will fail to find Korean friend (it is possible actually, but very difficult). Despite the social life in KAIST (which is not existing in KAIST), the academic part is outstanding. After graduating KAIST, there will be a lot of opportunities and in KAIST you will professional in studying 24/7 without any sleep. Good Luck!
