What is the flow of a math class?
300-500M m A math class has a traffic of 300-500M m. Take Tencent Classroom as an example. It takes about 300-500mm to watch a 45-minute webcast class in SD mode, and you can watch the webcast class in WiFi network environment. The traffic consumed by online classes depends on the clarity and duration of the video. The clearer it is, the longer it lasts and the more traffic it consumes.
