Choosing this course was a godsend. I am not a major, and I started studying late because I had a dream of pursuing IT, so I quit my job at a good company and started studying. I am attending a government-funded academy, but the pace is so fast and the lectures are so out of context that I don't know what I know and what I don't know, and since I don't understand, I wonder if I can't do it... I was frustrated all the time. I definitely listened to the lectures diligently, but I just tried to understand without understanding why the program was used or how it was utilized, but the knowledge I gained that way has left me with almost nothing as the government-funded lectures end. In fact, I took this course because I thought that Spring was so difficult, but I would learn it if I listened. However, what I learned while listening was, "This is Spring!" I hit my knee and said, "This is Spring!" The class was really fun because they explained the principles and why they were used step by step. This is the first time I have ever smiled while listening to a class. Although I knew it in pieces, the knowledge that was not connected to each other was connected, and the idea that this could be used in practice expanded! It felt like a thousand troops had appeared to me, who had no acquaintances or knowledge related to development. In addition, when I left a question, the instructor answered it kindly, so I can't tell you how grateful I amㅠㅠ I think that when the national scholarship class is over and it's time to prepare for employment, all I have left is Spring. This class is a ray of light to me to that extent. I was so impressed by the instructor's lecture that I already paid for the next lecture, and I think it might be the most valuable purchase I made in 2020. Thank you so much!
