I listened to all the practical lectures, whether long or short. It was hard to learn quickly in a short period of time before the end of the vacation, but it was fun to learn. The lectures themselves were very informative and good. In order to understand properly, I think I should not just listen to the lectures, but also do toy projects and review the lectures to study the concepts I forgot or the confusing parts again. Before watching the lectures, I felt vague about the Spring and Boot frameworks, but now I feel confident that I can use them. I haven't seen the theory part of other curricula yet, so I will take the time to listen to the lectures and study. If I had about a month more vacation, I would have been able to watch the entire curriculum. I regret it... haha Everyone may feel differently, but thanks to those lectures, I think they helped me grow a lot in terms of Java, Spring, and JPA backend technologies as well as in terms of overall design and structure. As a student who has never worked in the field, I worried about how to design and what method would be more correct and better code. There wasn't much progress, but it was good to be able to see it indirectly through the lecture. And I personally liked the stories that were told outside of the lecture content, not just in the querydsl lecture, but in the entire lecture. It will take a long time to watch the remaining lectures, but I will continue to study little by little and grow. Thank you.
