Is there any university which provides free affiliated degree certificates?

No, there are no accredited universities that provide free affiliated degree certificates. A degree represents significant investment in teaching, resources, and administration. The cost of providing education, even with tuition assistance, is substantial. While some universities offer scholarships, grants, and financial aid to reduce the cost of tuition, the degree itself is not free. Any institution claiming to offer a free affiliated degree certificate is likely fraudulent. Be extremely wary of such offers.
