It's a very helpful lecture.

I'm not a major, but thanks to you, I passed the written exam on my first try!! I'll work hard on the practical exam too.

It was helpful!

There are many garbage lectures where people are busy just reading lists without explaining the principles, but this one is great because it structurally explains why things are the way they are. Honestly, after studying programming separately and watching this, once I gained some structural understanding, I thought "Oh, so that's how it was." After that phase, it became so easy that I wondered, "Can it really be this simple?" Anyway, it's a masterpiece.

Thanks to you, I passed the written exam. Thank you!
