Dear Aspirant,

It is quite hard to predict the exact situation as it depends on the number of students attempting the exam the preferences of the students and the seat matrix of the college.

There are no official cutoff details from IISERs hence the predictions are based on the experiences from the past.

There are 1300 seats reserved for BS MS courses in IISERs.  Based on this we can say that you have a decent chance of getting into Berhampur, Tirupati campuses in the last and post allotment rounds.

There are always a small chunk of students who leave after getting admission into the college as they get Medical/ engineering colleges.

Please check the link below for more details.

IISER cut-off

Hope this helps.
