my question is , is it important to get admission in big universities like MIT, harvard, and get degree from these universities or I can get admission in small universities of my choice and gain knowledge equivalent of these toppers, and big universities students,
knowledge vs degree from MIT.
what are pros and cons in both(regular universities and MIT,harvard,etc)
Acquiring right and sufficient knowledge is more important. It doesn't matter where the knowledge is acquired from. What's important is to be refined and qualified.
If it were possible to even "self study" and go to such big universities to be tested for true knowledge and qualify for their degrees/certificates, in a short period of time, I would encourage people to go for it.
