Hi Amanj, the cutoff varies every year based on various factors like number of seats available, number of test takers, difficulty level of exams etc. However going by the past records, I would say it would be 50-50 chances as there is variation in cutoff actually. It switches between 500-550+ for SC and it all depends on the performances in further rounds on selection.

it is tough and very difficult in this situation for a call from barc.

I hope this helps. all the best.
