Everything was good, but I have about 5 major complaints. When asked if someone who doesn't know how to code can take the course, you confidently said, "Yes!" But in fact, even if you know Java, HTML, CSS, JavaScript, etc., this course is too fast, and rather than explaining things in detail, it seems like you just skipped over the minimum explanation for clone coding. Of course, it's a free course, so it would be greedy to expect more, but I wish you had at least written one phrase, "You need to know this much to understand" in the prior knowledge section. Thanks to you, I was able to finish it all in one day.
