I took the class to learn RPA, but it was great to learn more about Excel functions. In particular, the Excel functions are so useful that I think I will be able to use them well in the future. The lecture materials and explanations are also very clean! This is my first time taking an Inflearn class, but I really like the speed, subtitles, scripts, notes, screenshots, curriculum, etc. Thank you so much for organizing an interface that is good for listening to lectures!
