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.

It was a very precious time being able to learn product cost calculation through Excel materials used in actual practice. It was such a great lecture because the content was based on practical Excel materials rather than theory!
