Hi Ankit

The cutoff depends on a number of factors which are:-

No of students appearing in the exam

Difficulty level of the exam

No of seats available in a college

So , the cutoff can't be predicted on the basis of last year's cutoff .it changes after every year as

In 2018 it was 511 marks for sc 

In 2017 it was 481 marks for sc

Wishing you luck for the future.
