I wanted to organize Excel functions and this was the perfect course for that. I especially liked being able to review once more through the challenge missions and live lectures, and thank you for the easy-to-understand explanations.

It was an easy-to-understand and easy-to-follow lecture! The ChatGPT tips seem like they'll be very useful in practical work :)

The instructor approaches topics logically and explains them in detail in an easy-to-understand way. And you are so meticulous, and even during challenges, you provide such good feedback and emphasize important points very well. Thank you 😊

The detailed explanations through examples are very helpful for easy understanding.

It was great that you taught us how to identify the tasks that need to be done first in each situation and ask AI step-by-step questions systematically. I was curious about VBA code but felt burdened about learning it from scratch, so I took this course. Thanks to the course, I'm now reviewing my personal materials and asking ChatGPT all sorts of questions to organize them!
