I prefer online classes because It gives extra time for other work. If someone is eager to learn, he/she can learn from anywhere. Why do we need physical books when we have PDFs?. We don't use letters anymore because we found better alternatives. Maybe someday there would be no physical institutions. It's not needed to memorize everything and keep it inside our head, the real deal is getting things done properly. It's tough for a student to become financially independent because of physical classes and everything. Lastly, I want to say when we don't make education compulsory and pressurized, It becomes valuable. If we look back at the age of discovery, we can see education was not mandatory. So capable people did their studies of their own will and discovered all the great things we use. It is more appropriate to code something and submit it via GitHub. Memorizing them and writing on a piece of paper doesn’t make any sense. Similarly, If online questions are more analytical and practical, then copying somebody’s won't work anymore. We don't need to understand 100% from the university. There are millions of people out there to help and to teach. Education should be open for all, not inside four walls. So we should have the mentality to learn from any situation and from anyone anytime.
