I listened well. Thank you. I hope you could also release a deep dive course sometime. One that's full of theory + practice haha

It feels like I'm learning the reasons behind things I've been using naturally. I have a slight regret that I wish it had gone a bit deeper into the content. The lecture is excellent!

Good~

It was good

You explain things very well.

It was a beneficial time to solidify the fundamentals.

Easily and well explained.

I was disappointed because the depth of the content felt shallow compared to the price. Considering the target audience is people who can handle SQL to some extent, there was a lack of substantial content. I had certain expectations for the lecture based on the table of contents, but after hearing the phrase "It's covered in the SQL tuning course, so we'll skip it" about four times, I started to wonder if this lecture was just to promote the SQL tuning course. At a price of 130,000 won, it doesn't feel cheap, so I'm disappointed.
