Hey,

Unfortunately you can't pursue MA in Korean language directly without doing your bachelors in the same. Infact for masters in any foreign language you need a bachelors degree in it.

To pursue MA or M.Phil you must have completed BA in Korean language with a minimum of 45% marks overall. For getting into a BA course for foreign language, there is no specific exam for that. It actually depends on you. If you want to take another BA course and select Korean language as an elective subject, then you can go for it and give a relevant entrance exam for the course.

Hope this helps.
