Dear candidate most often after the declaration of the cut off the revised seat allotment process, there is no chance that the cut off will be shuffled. This is because the cut off principally depends on The number of students appeared in the exam, the difficulty level of the exam in that specific year, and since you are 20 marks back, to ensure the cut off it is near to impossible for the cut off to come down, still hope you can make it in the upcoming year.

Good luck!!
