Respected sir,

It's depend on the number of vacancies, psus have.

I think this time cut off will be more than the previous one, safe marks for psus is above 75 or under 500 rank. You can expect around 500 rank for 75-77 marks and around 200 rank for 80-82 marks.

above 70 marks for many psu. But for other top psu rank within 200 is safe.

Best of luck for your future!

I would suggest you to go through the below link to check the previous year cut off trend for the same-
