Generally speaking, you can't have it in college. Moreover, the level of Korean course teachers in the school is not as good as that of professional training institutions, and its practicability is poor. After all, Korean is a skill, and good communication skills are useful.

In my spare time, I recommend learning Korean video tutorials recorded and explained by experienced Korean teachers, with pure and authentic Seoul pronunciation, no need for online learning, direct mobile phone playback, unlimited time, and lifetime validity. Seoul National University Korean and Kyung Hee University's new standard Korean textbooks are adopted. The former is suitable for oral learning, while the latter is suitable for studying abroad by examination.
