Jinwoo, thank you for the great lecture review! You are preparing for your master's degree. It is true that you need to go to graduate school to properly learn circuits and handle more complex structures. Of course, a master's degree is not just about researching for the rest of your life, but you also need to increase sales through mass production after getting a job, so perspectives and understanding of products are still important, and I hope you gained a lot from this lecture. Good luck with your master's degree and develop your circuit technology even more!!
