E learning

No, physical classes won't be replaced by online classes in the future. First, physical classes have their own pros, such as being able to SEE and hear the teacher and the interactive way of learning a new concept. Second, online classes can be more time-efficient. You can cancel a class anytime you want and there is no need to worry about traffic, what you wear, etc. It is easier to make live connections with other students when you go to physical classes. But, the best thing about online classes is that you could work at your own pace. So if you are in hurry to finish your degree, online classes might be the best option for you.
