All our courses are important and useful, but we separated the Essential Curriculum to emphasize the importance of the courses and to help you build a strong foundation in learning Korean with TTMIK.That is why we separated them from other courses.
The courses in the Essential Curriculum are the core courses that we carefully planned to help you learn Korean more effectively. Thus, you can use the Essential Curriculum as your main study material and supplement it with other courses to enhance your overall Korean language skills.
