text: As day by day passes, I believe that lots of students are sick of repeating the same dull sketchual, and wish they could stay at home for school, on the other hand, they will not have to wake up so early everyday when they worked on their homework till so late. When students attend classes from home, they will be able to manage their own sketchual, learn how to control their time efficiently, be more self-reliance, and prepare for the future.
