Is Madison hills university is genuine?

There is no known accredited institution called "Madison Hills University." A quick search online doesn't reveal any legitimate university with that name. This strongly suggests it's not genuine.

Before enrolling in any university, especially one you're unfamiliar with, always verify its accreditation through reputable sources like the U.S. Department of Education's database or equivalent bodies in other countries. A lack of accreditation means the degree earned may not be recognized by employers or other institutions.
