The mic quality is also disappointing, and the explanations are just copied and pasted and skipped over, so there's not much that stays in my head ㅠ It was an opportunity for me to learn how good other people's lectures are!

It helps a lot.

The sound quality is also the worst, and I just read the guide while playing, so if I had known it would be like this, I wouldn't have bought it...

The audio quality is bad and the speech is often slurred, so it's hard to hear. The official document is simply read verbatim, but I paid to hear the explanation in a different way, but it's meaningless. The material organization and useful links are good for each lecture, but the video quality is so poor that it's easier to learn if you don't watch it.

I can't even hear the voice very well, so they just read the guide page~
