Thank you for the great lecture. I learned a lot. However, it seems unreasonable that you can watch the lecture after writing a review for the Section 9 lecture and the instructor reviews it. If you have previously paid for the lecture, you can just ignore it as a bonus lecture, but if you paid after seeing the curriculum, you are a little confused. I heard that you worked hard to film the good lecture and are preparing a new lecture, so I hope you prosper.
