I'm a first year middle school student learning front-end development on my own, and since there aren't many good free lectures, I quickly finished them and looked for paid lectures. I started with the Daebang Industrial Development site because it looked cool, but it was fun to learn from because it explained things in detail and even touched on parts that I couldn't learn well from the free lectures :) It was a really fun lecture, and I think middle school students would be able to complete it if they work hard! I really liked how J. Young kindly responded to my requests for schoolwork and consistently answered my questions!
