The lecture is a bit... well... The video explaining @Controller is 15 minutes long, but the actual explanation doesn't start until the 6-minute mark. For the first 6 minutes, it's just clicking through directories back and forth. I believe a technical lecture should be systematic—covering definitions, necessity, how it works, and coding techniques—but this doesn't seem to be the case. Many people seem to like it, but it's not for me. I feel bad for pointing out only the negatives, but I have to be honest about my disappointment.

Thank you for the great lecture!

This is a video that explains things easily and well, suitable for beginners.

I'm a beginner who has tried various SQL courses here and there but ended up giving up. With this course, I haven't given up yet, and everything is going into my ears smoothly, and the hands-on practice is progressing well too. Thank you for providing such an excellent course.

The lecture materials and the sections in the lecture are not synchronized. For example, the lecture material says "#Section3 [Practice] PL/SQL Just This Much," but the lecture is classified as "Section 4."
