Stopping the lecture here and there to create SQL directly myself makes it much easier to understand. Since it's not long, if you study while listening to the lecture at a relaxed pace, you'll find that your anxiety about SQL has disappeared before you know it! Fighting to everyone listening to the lecture~!

The lectures are so easy to understand and comfortable to follow! It's not boring at all, and I understand it so well. The explanations flow like water!

If you want to have a basic understanding of SQL, I recommend you take this course.

Good lecture. Please be sure to give intermediate or advanced level lectures too, even if you are busy.

The basics are well explained.

I like it because it's a very informative lecture that can be completed in one day.

The weighting was appropriate for the level of importance, and the clear examples made it easy to understand. I was able to finish the course in two days. Thank you!

Thank you for the detailed explanation.

I trusted and listened to Professor Lee Jang-rae's class, and as expected, it's the best :)

Good!!
