Guru Gobind Singh Indraprastha University — regarding the document verification while registration

In an official website, it is not mentioned regarding the affidavit for the gap year. Also for character certificate, if the heading "character certificate" is not mentioned but entire certificate is correct, it gets rejected inspite of having signature and seal of the gazetted officer. Mode of payment is not mentioned in official website so when we propose to pay the due with cheque it is rejected outrightly. So it is not possible for the outstationed student to present with the correct document or mode within a few hours. Unless everything is clearly mentioned in an official website
