To give a more precise indication, I watched maybe the first 5 minutes of lecture 1 and 5 for this.
I highly encourage you to take "didicatically useful" as a bar to aim for, rather than "not making mistakes".
I think it's a cool tech demo, but if you're positioning this as a course that's ready to be consumed by students, I think doing the quality control is not optional.
Thank you for the feedback! We'll make it better. We take quality very seriously.
