[Advantages] 1. Suitable for beginners to Power BI. 2. Detailed explanation. 3. The lecture is not long, but it contains the core content well in the short lecture. [Disadvantages] 1. It's short but expensive. (* Although there are some lectures that are over 30 hours long and cost around 100,000 won, this lecture is considered expensive compared to its length.) 2. It may be my fault for taking this lecture in 2024, but it's a lecture that was made a long time ago. The layout shown in the lecture is quite different from the current layout. (* Nevertheless, it is helpful enough.) [Overall] If you are a beginner and don't care about cost-effectiveness, it is a great lecture.
