The thing is poly grads and Uni grads should be given the chance to ascertain their credibility,however equating the certificates will not be okay because the structure of university n poly is different for example in poly u dont have Cgpa i.e cumulative grade point average from 100level to 400level(8semesters) in poly u can get a lower credit result in nd and get an upper in hnd,i believe they are different u cant equate them seriously those guys in 200level direct entry from poly can verify.
