after paying partial admission fee ,ist here any document verification
Obviously!
Once you will join the college , there will be an offline verification of documents where the original documents will be checked with documents that are submitted online. If all the documents are verified then the admission will be fully accepted and you will be said to be the provisional student to that college. After the registration in university then you will be called to be the student of the college.
This is the general process of admission. Although there may exist some exception.
I hope my answer helps you. All the very best for your future endeavors!
