Hi,

A recognised university is one which is approved by UGC. There are many universities which are not approved by UGC. The degrees of such University are not approved in any government exam and college admissions. Many other reputation institution also consider this ineligible if you're college is not approved by any government  body.

Hope you find this helpful.
