I am a student in a department related to digital media. There are some parts that I learned in my major, and the rest are expanded content, so I listened to it with interest. First, this lecture is not too specialized and doesn't make you feel dizzy. Second, it doesn't just skim through the basics and leave you confused. It is a lecture that maintains a great balance. Although the lecture is less than 3 hours long, I felt that the teacher put a lot of effort into the content.  ✔The lecture slide PDF is visually clean ✔The teacher's voice is clear ✔It is moderately detailed and moderately fast, so it is not boring, but it is not poor either These three strengths alone made the lecture worth the tuition. Since it is a lifetime pass, they said they will also update the lectures, so I will come back later to review.
