Before taking the course, I had no information or knowledge about the Mixpanel tool, so I didn't know how to use this tool and was overwhelmed. There was a Mixpanel course on Inflearn, so I took it, and it covered detailed features and usage methods, which helped me improve my understanding of the Mixpanel tool! I had no experience using data tools before, but thanks to this course, I think I'll be able to utilize Mixpanel in the future! I was able to reduce my overwhelm about data tools! I completed the course quickly, so I'm planning to review again how to check data and charts! Thank you for creating such a useful and substantial course!!
