I have backlogs/arrears during the qualifying degree program, due to which I did not complete the program. I am currently not studying in the college and therefore cannot get duly signed Certificate from the Head of the Department/Institute. Which document should I upload while filling the application form?
If you cannot get a duly signed Certificate from the Head of the Department/Institute, you should submit final year marksheet (of any one semester), even if there are backlogs/arrears in some subjects.
