A degree from South Korea is not valuable outside from South Korea, although a graduate with good marks in a certain field. According to outside sources I found, "international tests" have a good chance attending a university for postgrad work.
Korea’s government decided to make higher education available in the 70’s and 80’s.
Korean high school students study themselves a lot to get into a good university. This determines your life prospects and parents push the children extremely hard.
students in the ‘non-advantaged’ majors was desperate, fierce and often underhanded.
So these anomalies account for why the higher ed system in South Korea is not always recognized in other nations - specifically the West.
