There are many advantages, disadvantages are caused by learning online. While the COVID-19 pandemic was happening, lots of schools around the world were choosing to learn online instead of going to school. That's the best idea that I've known. As a result, students still gain enough knowledge and school work. Moreover, parents won't take so much time to drive students to school. Students can wear any clothes and don't have to worry about forgetting to do homework or forgetting books. 

On the other hand, students also have some disadvantages. Some students will fall asleep or play games while learning. Maybe some teachers don't mind: there will be some "bad students" attending the class but they are always doing other work while learning online. Besides that, students will have sore eyes if they watch the screen too much.

In conclusion, online learning is the solution for quitting days at school but there will be lots of benefits and drawbacks.
