Thank you for your review. If I were to remake it with the same curriculum, I think I could do a little better, but since it was my first lecture last year, there were some awkward parts. Above all, it was difficult to set the target. Should I target people who know a little bit? I'm still worried about this part. I plan to update this lecture by adding a little more to the parts that I couldn't explain in detail. Have a nice day :) - I renewed the lecture. Please take a look again~
