i have not marksheet of highschool because my marksheet is under up board office for correction in my father name so how i upload marksheet.

Hey Kaushal,
Since, you have given your highschool mark sheet for correction, so you don't have the hard copy or offline copy of your result. So, you can just upload any online copy of your mark sheet or if you have any image of the result, then you can upload it too. It has the same value and will be accepted as well.
Hope this is helpful and good luck!
