The instructor's lecture is really good because it's easy and detailed so that even non-majors can understand!! Especially the visual materials you drew yourself are truly a great help 😭😭😭 You also answered questions quickly, which was good. I feel so proud because I feel like I understand threads and synchronization, which were difficult and I was very curious about, to some extent. I think I'll feel confident when the situation arises where I can incorporate it directly into practical code!! :)
