Ah, this is a lecture that I had high expectations for and purchased. I was excited from the first lecture because I thought I would learn so much in this short class. But that was all..ㅠ It is suitable for accountants or bookkeepers who are starting to study taxation. And for freelancers and self-employed people like me who want to get some great tips on tax processing, I don't think you will get much out of it after watching all of this. The tuition fee seems expensive compared to the content of the lecture. However, the lecture style is good, so I am looking forward to the book. It is a bit old, but I would like to read it someday if I get the chance. Thank you for the great lecture.
