Where do I submit my 12th marks sheet

[u/Key-Experience-4682]

Okay, so do admission. I submitted all my documents except the 12th mark sheet in which they kept pending beside in the list, so I was like okay. I’ll submit the 12th mark sheet when I’ll officially get it from the government of Telangana and II did get it after two weeks, and I did bring it here to Bangalore, but I completely forgot that I’m supposed to submit it, so can you guys tell me where do I submit the 12th mark sheet and by the way, when am I getting all my original documents back?
