The teacher's voice is soft and the speed of speech is not fast, so it was easy to concentrate in class. The pronunciation is also clear, so I was able to take the class without difficulty even though it was a lecture where I couldn't see the shape of my lips. When I prepared for the coding test on my own, I felt like I was just wasting time and not improving my skills, but since you explained the method of approaching the problem step by step, I think I understood just by listening. I haven't finished the course yet, but it seems like I'm organizing the basics, unlike when I just solved the problems. Thank you!
