This is a great course for the price. Since it focuses on UI from the basics to advanced, you can fill in the UI parts and optimization that were lacking in existing Unity courses with this course. The price of 10,000 won is not a burden. However, since all the courses have background music recorded quite loudly, it would be a good idea to preview them and check if the background music is not bothersome. There are some courses that are out of sync. However, overall, the instructor's explanations are good, and the tip courses provided later are secretly helpful for beginners, so I think I can recommend this course.
