Dear applicant genuinely to understand or get an overview of the cut off you need to know the fact that, each year's cutoff totally depends on the number of students appeared in the exam, the difficulty level of the exam as well. But if you just want to have a perception of the cut off, based on past few years it has fluctuated within the range of 80-90, and in the upcoming year you can genuinely expect it would be more unless the paper is extremely difficult.

Hope it helps!!
