I finished reading it once. It was quite efficient to listen to the lecture while going back and forth with the JPA basics. Thank you, Younghan. It was very helpful! Now, I'm going to listen to the 2nd part of the application and review the basics again! I felt the importance of reviewing the basics because I felt the need for the basics every time I got an error while working on a personal project. Reviewing the basics, the application, and even Spring MVC 2. There's a lot to study. I'm so happy that there's still a lot of room for growth. I think my skills are growing thanks to the great lectures! I'll work hard and become a great backend developer in the future. Thank you :)
