If a person can self learn the subjects and appear for the exam's only to get the degree. Second Why PhD from anywhere in the world with only minimum fees for final processing Based on once individual research done and can defend the thesis only based on his individual capacity.
Why are degree's more commercial to acquire from a university until the tutor in the university is being used the candidate to study.
Atleast big one university in each country or the world should be self independent acquire atleast PhD from anywhere.
