This course is really great! There are so many great tips that even the salespeople don't tell you, so I've gotten off work much earlier. I started with the basics of marketing and learned dashboards that can be applied right away in my work. In repetitive tasks, I used to spend a lot of time just copying and pasting numbers, but after learning Google Spreadsheet query statements, my work has become much easier. Thanks to that, I have more free time! After taking the course, I also got a GA4 certificate, and I'm applying the marketing dashboard I created myself to my work, so it's very convenient and useful. I definitely want to take intermediate and advanced courses in the future!
