I took the class because the lecture table of contents seemed to be well-organized with a wide spectrum from the basics to application and utilization, and each lecture seemed to be better organized than I thought. It's good that you explain everything in detail from the basics. Also, it's even better that you answer frequently so that the community doesn't die. If I had to point out a disadvantage, it's that the speed is a bit fast..? You have to stop a lot in the middle, but it's better than being slow.
