It's been a long time since I registered for the course, but I could see the affection for the course as I steadily updated and expanded the course.. Honestly, I think I could just update it to some extent and leave it alone, but I think it's not easy for anyone to always receive feedback, revise existing courses, and add if they're lacking.. That's how good the course quality is, and it was nice to be able to hear a lot from this one course. I'd like to recommend it to anyone who wants to take a CS course!
