Honestly, I paid for about 6 lectures worth 50,000 won and completed them. As with all lectures, they give you a rough explanation as you go on, and if you just write code that is not explained and move on without explaining it roughly, you will end up giving up. This lecture does not explain all the codes perfectly. However, it is the most friendly lecture I have ever seen. And other lectures are the same even if you listen to them repeatedly. However, this lecture explains the script code so kindly that even if it is difficult, don't give up after listening to it 3 times and try it once. It was more effective than listening to 6 other lectures.
