This is a really difficult lecture for beginners. I have never studied marketing before, but I signed up for the course because I was interested. I think it's good that it's summarized in a concise and concise manner. However, there were a lot of technical terms, and I felt like they didn't explain them well, so I had a hard time understanding it. I think it's because I don't have any experience yet. I think it would be an easy lecture for those who have experience or have studied marketing.
