I suggest you study Korean outside at ordinary times. If you major in technology at university, it will be easier to find a job in the future. If you only learn Korean, you can't compete with Koreans. Without other skills, it will be more difficult to find a job in the future. If you want to learn Korean as an amateur, you can contact me. I have been studying in Korea for two and a half years, and now I have the idea of being a Korean tutor.
