I am currently working as a server and storage infrastructure engineer. The Big Branch certification is not very related to the field I am currently working in, but I acquired it because I was curious about the field and didn't know how the certification would be used in the future. While studying Python, which I learned briefly during my undergraduate years, I was struggling, but after listening to the instructor's lecture, I passed with a total of 90 points. Thanks to this, I was able to obtain the existing Jeongcheogi and Big Branch dual-engineer certificates. Thank you for the high-quality lecture. Thanks to this, I think I was able to approach it in a really easy-to-understand way. If I have time in the future, I will study big data and AI as my second major and work hard based on this experience. For those who want to acquire the Big Branch, I recommend that you take the lecture of Instructor Tanjit after work to obtain it quickly instead of studying alone and struggling.
