Sarah Ma, am, I am writing this comment after watching all of your videos. You are very precise and have explained everything so much in detail and clarity without wasting even a minute that my concepts are crystal clear. You covered all the aspects of the subject from basic to the complicated one and its relation to each other. your classroom setup and video editing is simple yet perfect. I request you keep posting such videos.
