Hello, Hak-yeol Kim. Thank you for leaving such a precious review! When studying with books or internet materials, information is often scattered, making it difficult to grasp the overall flow. I am glad to hear that the lectures are helping you learn more easily. I can feel your passion for learning in your comment about "learning through physical struggle," and I am truly rooting for you. As you grasp the concepts and flow through the lectures and gain experience through hands-on practice, you will find it easier and easier to understand. I will continue to support your learning journey until the very end. Thank you! 💪
