Hey,

The certificate that a college is valid to take admission of students in its college is given by UGC. So if your college of choice is UGC granted then all courses offered by the college will be considered valid.

Now coming to NAAC, it is a body that gives credit points to college that help college to gain reputation and enhances it's ranking. NAAC credits only tells how good the college is and not that the college is valid or not.

Hope that helps.

Thank you.
