Thank you for leaving a review, Jinwoo Lee. The point you mentioned is both a strength and a weakness of my lectures. Since I structure the course so that you can reflect and chew on the material later, I often hear that different parts stand out depending on the situation at the time. If you watch it again later, you'll likely discover new insights once more. :) Congratulations on completing the course, and if you have any questions later on, please feel free to leave them! Have a happy 2026. Thank you.
