I am a beginner who only learned the grammar of Python from other sites. I took the full-stack course of the instructor of Janjaemi Coding, and it was so good that he explained it like drawing a picture of the whole forest in a way that was easy for non-majors to understand. As I was studying full-stack, I needed to study SQL, so I started taking the course. Even though there were parts that I didn't know, I completed the SQL course from beginning to end. After doing it, I realized what I was lacking. I understood the other parts and moved on, but I lacked the ability to apply them to crawling. I am satisfied with the course~ I will go to the next course as well :)
