The last type of study - wild type/scholar type - I was completely wild type. After servlet jsp, I went straight to spring data jpa and even did a project, but I felt like I was lacking in the basics, so I was looking for a lecture and took this lecture, and I really enjoyed it. At first, I thought my study style (wild type) was wrong, but after listening to the last lecture, I realized that this was my original style and it gave me strength. Still, the lecture content wasn't something I didn't know at all, but rather something I didn't know, so I was able to finish it in 2 days! Thank you! It's a choice I don't regret for building the basics!
