Initially, I felt that what I was learning in school wasn't enough, and that's when I came across the lecture and started studying. As I started the lecture, you gave examples of where and how PCB HW-related skills are actually required, which made it even more interesting to study. Also, even though I don't have much knowledge in the field, I was able to easily understand the systematic process tailored to the actual development flow, which was great. It was very helpful for me as I have not yet experienced practical work.
