Generally speaking, Busan University is not bad among local universities. But it also depends on what major you want to study as an undergraduate, whether you go to Seoul or a local university. As far as Bozan University is concerned, Central University in Seoul Circle and dongguk university are very good.
Busan University is an absolutely famous good school. Busan is the first school in Korea, except sky. If someone is a professional, I suggest you choose what you like, because college is really boring and not interested. Then there is the question of whether the major in Busan needs foreigners, because communication may be difficult. I hope you can find a more suitable major. Come on!
The environment is really beautiful. Busan University is built on a mountain, and a small mountain spring flows from the top of the mountain to the main entrance at the foot of the mountain. There are big stones on both sides of the mountain spring, so you can sit and lie down. Occasionally, I can see foreign students sitting there drinking coffee and chatting, or laying a mat to practice yoga. The trees are lush and there are magpies and squirrels everywhere. Squirrels sometimes fly between the two trees above you. Fortunately, I can still see deer and wild boar, and some students say they have seen bears.
Busan, a city surrounded by mountains and seas, has no tourists from Seoul, but it is not as rich in cultural life as Seoul. Many plays, exhibitions and concerts can only be seen in Seoul. Before Degang Guo came to Korea, he had only been to Seoul. However, the scenery in Busan is really beautiful. In spring, you can see winter jasmine and cherry blossoms. Surfing in the sea in summer, and seeing Beomeosa Temple full of red leaves in autumn (Beomeosa Temple and Busan are not far from a mountain); Eat roasted shells in winter and watch the light show in Yuntai and Nanpudong all night.
The biggest gain of studying abroad is nothing more than being able to live independently, get along with any strange environment and get along with friends. A degree certificate is naturally important, and a diploma from Seoul National University is indeed more weighty. However, if you are not top student and have no greater desire, you can consider coming to Busan University, and you will like the slow pace of Busan.
