Hello, I'm a middle school student who completed the entire beginner course! (I don't know where else to write course reviews, so I'm editing what I wrote in the old place..) First of all, it's no exaggeration to say this is truly the best lecture that exists. Although I had coded before so switching languages wasn't particularly difficult for me, the teacher explained the characteristics of Java commands "clearly," making it so clean that I really don't need to watch it again. Most importantly, having lecture notes available allowed me to refer back whenever I didn't understand something. You can really think of it as Java = Kim Young-han's lectures! And because the beginner course was so good, I bought all of them: basic, intermediate 1&2, and advanced 1,2&3 😊😊
