What are the chances of change in marks after revaluation?

Hey! I have got my result today..I fell short of 5 marks..In accounts I was expecting an exemption but scored only 46..It was a shocker..In no circumstances I imagined such low marks especially when I compare to my friends' marks in the same subject now..I think something is wrong with my paper..My hope is revaluation..Has someone benefitted from this or is this for name sake only?
