I completed the course and am leaving a review. The lectures were short and summarized only the key points, so I was able to finish quickly. With other lectures or books, you can sometimes learn several mathematical applications, which broadens your perspective, you know? I had those expectations for this course as well. However, looking at just the curriculum, it seemed difficult to expect anything special, so I hesitated a lot before purchasing. From the preview, it seemed like the teaching style would assume basic knowledge, and all my predictions were correct. So this course might be difficult to complete for those who aren't confident in math. That said, it doesn't cover difficult content, and although I'm not good at math either, I was able to understand all the formulas and solutions presented in the lectures. What's disappointing is the question of whether the course is relevant enough to include some Unity engine lectures - I don't see why Unity lectures need to be in this course. The examples are already well-known content like textbook material, and if anything, the content has been significantly reduced in this course. Unity itself isn't even needed in the latter half of the course. It seems the instructor wanted to provide a foundation so that if you have the knowledge introduced here, you can use math for problem-solving, but I think the curriculum might be flawed. The direction of the course was confusing to me. Excluding the occasional talking to himself, the lectures were clear and the intentions seemed good, so I gave it 4 stars.
