Marks(imp pls)

u/rowlet-owl or someone please help.

I got very bad in signals lower than what I thought my worst paper was which is ACD the thing is this was my second best paper or atleast I thought so but I have gotten way less lesser than average even my friends have gotten more than me by 8-9 marks is this some sort of ai grading or have they normalised the score because I am pretty sure I did enough to get 25 atleast.

Is there anyway to contact about this discrepancy or should I have to wait till revaluation if there is a way to check my marks please let me know as I feel like there has been a huge mistake in grading my paper
