I listened to this intermediate 2 lecture quickly, but I liked that the parts that I had roughly learned in school, such as lists and sets, were organized more systematically. At school, they just told me the results, but Teacher Yeong-Han explained the reasons in detail, so I understood them naturally! If I had more time, I would listen to the advanced part, but now that I am a job seeker, I will quickly move on to Spring. I will see you again in the Spring lecture!! Thank you.
