The degrees of all the courses either graduate or postgraduate in AKTU are distributed during the Convocation Ceremony of the respective colleges. There is a chance that your college did not conduct such a ceremony. In this case, the degrees are usually sent to the respective colleges which are kept there for around 2 years. After this, the degrees are sent back to AKTU, Lucknow.
To get your degree then the only option left is to visit AKTU personally and submit an application detailing your issue along with essential documents like mark sheets and your ID card. The Vice-Chancellor of AKTU is Mr. Vinay Kumar Pathak. He will help you in this matter. Go to his office and submit the documents and soon your degree will be handed over to you.
