I am making a blank project from scratch while listening to the lecture. It has been a long time since I listened to the Unity Engine lecture, so I was a bit vague, but it was good to review the contents I learned back then and remember them vividly. And there are tips that are hard to learn without going to the company. Personally, I prefer to study by thinking on my own rather than listening to the lecture, and I think the full source code is really helpful.
