This is a great lecture!!

I started taking this course because I use Excel a lot in my work, and it’s a great lecture that explains exactly the parts I was curious about and needed. Since it’s a follow-along learning style, it’s very easy to learn.

They say a thirsty person is the one to dig the well, but I feel like I've discovered a vast lake. I believe anyone who isn't in the finance department but has encountered management accounting out of necessity will agree that you put a tremendous amount of thought into making everything—from the lectures to the condensed materials—easy to understand. I was particularly struggling with how to express cost reduction in accounting terms, and this was truly a huge help. Thank you!!

There is not enough data!

It was a lecture that explained things easily.

This was a lecture that made theory and practice easy to understand by referencing tables.

All the lectures and materials provided are really well-made so that they can be applied directly in practical work. It seems like the best materials created through the instructor's experience and meticulousness. I will use them well. Thank you.

Analyzing variable cost fluctuations through production volume variance, unit variance, and unit price variance really helps clearly distinguish between changes due to actual cost reduction versus changes due to volume increases. This seems like it would be great to apply directly at my company. Since you've provided the materials, I think I'll be able to implement this right away at work. This is a lecture that's perfect for practical application. Thank you so much.

Since I didn't major in cost/accounting and was working at a company, there were many things that felt overwhelming, but you explained it in a very practical and easy way, which has been really helpful. The Excel customization has really reduced my work hours by about an hour. It's absolutely amazing!!

It would be better if you could provide both Korean and English for frequently used terms. Also, you sometimes use overly hasty and disorganized expressions that make it difficult to understand at times.
