During the first round, I couldn't understand what was being said at all, nor could I grasp the purpose or meaning behind why things had to be done that way. From the second round, I started getting used to it and became able to carry out projects on my own, finding the necessary parts as I went along. By the third round, since I was watching with a solid understanding, I was able to enjoy the lectures, unlike the difficult first round. It’s a huge help that you update new lectures quickly according to the latest trends and provide great answers to questions. Thank you for the excellent lectures.
