I recommend it! Above all, it's fun, and the instructor is so bright and fun, so I feel good every time I listen to the lecture! He explains everything in detail, so most of my questions can be resolved during the lecture, and even if I ask a question separately, he answers it very carefully and kindly! I feel that he has a really deep understanding and ability for all the content he lectures on, and I think it's a really good lecture that makes my head spin because every word contains information. I learned Spring superficially in the past, but I feel that many of the questions I had while learning at that time are being solved every time I listen to the lectures. This is a lecture that I want to listen to over and over again!
