Online classes also lead to students surfing the net when they need to study or do their homework. This is one of the greatest cons of learning from the comfort of your home. Whereas, in the case of offline classes, students need to stick to a strict schedule.
Offline education is the traditional counterpart to online education and the original method of learning that allows students to have regular face-to-face interactions with their peers and teachers. As much as online education is predicted to be the future of learning, it cannot replace the holistic aspect of offline education.
Being in an online class, students can access the class from anywhere as long as they have intemet access. So that means people from everywhere can take that one class in the same school. In traditional classes, people from all over the world can move and go to that same campus that you are at.
