rein-'s honest review, Excel data utilization and analysis know-how that makes work 100 times faster course

It's good for learning and practicing because the core concepts are explained easily and well! I forgot many Excel features I used while doing marketing work for a year because I didn't use them. Feeling like I needed to reorganize, after taking the 3-hour core lecture, I'm now taking the data management lecture that makes things 100 times faster. Afterwards, I plan to try learning the 8 practical examples lectures or visualization expressions while reviewing at least twice! Thank you:)
