In general, the program is good, but it is research-oriented. This means that the main focus will be on your research and your life will depend on the lab you will be assigned to. There are various courses, but usually, professors don’t pressure graduate students as they say that the main goal of a graduate student is doing research. And as it is an Asian country, in some labs workload and expected working hours can be crazy. So I would recommend choosing your lab wisely and asking people around about the professor and lab atmosphere, because you will spend most of your time here (you have working hours like from 9 am till 6 pm). The international community might not be as big as in the US, but it’s becoming better. I enjoy my social life here a lot. And if you like living in busy cities, Daejeon might not be your option, it’s mostly very chill.
