It's good for grasping concepts well.

It was a very helpful lecture for my practical work.

The words are difficult and the speech is long

The first time I listened to it, I listened to it for general understanding, and the second time I listened to it, I gained confidence in disco. I think I will be able to practice and apply it after listening to it for the third time, so I will listen to it again. ^^

Thank you~!
