hello aspirant

Cutoff rank for any college is the benchmark ( minimum) rank required to get admission in that particular branch of that college. In due course all the seats available of a particular branch in a particular college are exhausted. The student who selected the last available seat before the seats got exhausted, holds the biggest rank in that branch, and that rank is the cut-off rank for that branch/college .

A grade cut-off refers to the academic average required for admission to a program . The cut-off varies by university and year, according to the number and quality of applicants

I hope that this will help.
