text: First, students can save their time by attending classes from home. They don't have to wake up early in the morning to get the bus, to shower, and etc. By saving time they can sleep more; if they sleep more they will pay attention to what they are doing. There is so many students those fail their classes just because they don't pay attention in the class. For example if teachers ask them why they are not paying attention most them answer "i didn't have enough sleep." So Students can save their time by attending their classes from home.
