I've taken many online lectures, but the flow of the lectures is really good, and the style of the lectures that starts small and then changes continuously is really good! There are no parts where the flow is interrupted or the content suddenly goes off the rails, so it seems that the lecturer has prepared a lot for the lectures. I paid for the online lectures last year, but since they are lectures that I need at this point, I recently finished them all at once. There were many parts that I applied to my work, so they were really helpful. Thank you!!!!! If I need other lectures, I will definitely take Captain Pangyo's lectures.
