"If you study properly once and take the time, it will help you for life!!" The instructor's words are stuck in my mind. I was worried about whether to take the class or not because the content is so vast. If there is a lot of learning content or the class time is long, the learners and the instructor usually get tired, but wow... The instructor's tension is not ordinary. You can tell that he prepared a lot just by looking at the PDF lecture materials. I also like the curriculum that includes practice after learning the theory. I haven't even taken half of the class yet, but I will study diligently and finish it. I will also study part 1 and part 3 to create a web server that can be used for service. Instructor! You worked hard. Happy New Year!!
