I was a complete beginner so I gave up halfway through, but after learning about Jaeseong, I started following from the basics. I almost cried, but he taught me all the essential concepts and taught them in a very easy way, so I was listening to the class with a smile! Jaeseong's lectures are so great because I understood everything right away! And the best part is that after listening to the lecture, when I study on my own, I don't have any other questions or concerns because he explains it so well, which is great~! If there are any beginners who are worried, I recommend you to definitely listen to it~!
