I learned Unity Editor basics from just one book on absolute beginner courses before taking this, but it's very difficult. The explanations are very good. However, since this course proceeds assuming you've taken prerequisite courses from earlier lectures, there are many parts I don't understand, so I could barely follow along with the code sections. Even just copying the code to make it run properly took me about 3 times longer than the lecture duration. I think it would be very helpful to go through it a 2nd and 3rd time, carefully examining the code.
