I passed the 4th technician exam with a score of 95! I was studying on my own with lectures on YouTube, and I happened to find this lecture, so I studied for a month before the exam. At that time, I was also preparing for another technician exam, so I didn't have much time. So I had a lot of concerns before paying. If there are people like me who want to prepare for this exam through self-study relatively quickly, don't worry and take the course right now. If you follow the lecture curriculum step by step, I think you'll definitely pass. It was a lecture that was good not only for preparing for the technician exam, but also for solidifying basic concepts related to web publishing. I'm also grateful to the instructor for giving such a great lecture :) +A brief review and certification of passing right after the exam https://www.inflearn.com/chats/362535
