I am leaving a comment on your sharp class review. It seems like it has been about 3 years since I made this course. I am always grateful that you are still taking the course consistently. I also agree with the parts you mentioned, so there is no room for refutation^^ However, when I was making this course, I had a lot of problems with my pronunciation because I was working on projects during the day and taking care of my children at night, so I mainly made and recorded the lectures at dawn. Thanks to your sharp comment, I am reminded of why I had such a hard time back then. ㅎㅎ (I guess Kubernetes was that fun^^) I am currently busy with a project, so I am focusing on one thing and cannot make lectures consistently, but if I were to make another course, I will practice my pronunciation a lot and improve on the parts you pointed out. I gave the same answer to someone who commented with similar content before, but I will say it again. Because of those shortcomings, I increased the lecture volume and did not set the price high, so I ask for your understanding, and I apologize for tiring out your ears (--)(__)
