TIFU by accidentally dropping my test paper

So today we had an exam and it was a chemistry exam I live in India and in a NE state, after I had finished my paper and then went to go and submit it, i accidentally missed one paper and i forgot to clip it, after school ended (we had the exam on the last period of school) my friends came and informed me about it, I rushed back and saw the paper beneath the table where we had submitted our papers, I rushed to the teachers office and placed it at the corresponding teacher’s table later I informed him that I had dropped it (I texted him on whatsapp) he said there was nothing he could do about it and it was due to my clumsiness which I accepted but since I’m a newcomer to this school I thought there might be some second chance but NO! this teacher was really strict and now there is nothing I can do about it, the thing about our school is they call out the failures during the assembly, and I think I’m going to go out FML for this shit
TL;DR I ACCIDENTALLY DROPPED MY PAPER AND NOW IM FUCKED
