good. well structured coarse

It is helpful.

I highly recommend this to anyone currently learning SQL who finds it difficult. I gave up when I took other SQL courses, but after taking this one, I became interested for the first time :)

You explained it so clearly that I'm working hard to keep up!

The explanation is clear.

Even those who have just learned SQL for the first time can understand everything without any problems if they move on to the intermediate class after taking the basic class.

It's very easy!

It was very helpful because you explained Joins and Unions, the highlights of the basic lecture, so well.

It's a decent introductory course, but it feels like the short, entry-level content has been broken down into too many small segments.

The instructor explains things well, but I still don't quite understand the subquery logic.
