Korean is spoken by millions of people living in South Korea, North Korea and in several Chinese prefectures. However, slight differences in word usage and grammar exists between the Korean language spoken by South and North Koreans. Learning Korean also involves learning dialectical differences based on tonal and idiomatic dissimilarities. However, these dialects are partially intelligible and generally pose little problem when communicating in either districts.

In order to improve job prospects and learn more specialized information, many students decide to earn an undergraduate degree, such as a Bachelor of Arts. Certain schools allow students to earn a BA on a flexible schedule through online or part-time programs.

Part-time learning allows one to obtain a degree or qualification even if one cannot attend school on a full-time basis. One can learn at one's own pace, gradually accumulating credits that count towards a final qualification.
