Personally, I have never experienced the assignment-based course, but the feeling of the sample lecture was so good and the lecture table of contents was so impressive that I ended up purchasing it. The instructor did not say anything unnecessary and got straight to the point, which was also very satisfying. The lecture time was also compact, so only high-quality content was delivered, and I did not feel any of the distraction or lack of communication that I felt in many development lectures. Personally, it is one of the lectures I liked the most among those I took this year. I listened well. Thank you.
