Dear Aspirant,
It is not possible to make accurate predictions as it depends on the number of students attempting the exam, the preferences of the students and the seat matrix of the colleges.
As we don't have any official cutoff details the predictions are based on the experience only.
There are 1300 seats in IISERs that are reserved for candidates getting admitted via IAT.
About 250 seats are reserved for OBC NCL candidates.
Looking at these trends we can say that you have a fair chance of getting into IISERs in the last rounds. You have a good chance of getting IISER Tirupati, Berhampur or Bhopal and a small chance of getting TVM or Mohali in the post allotment rounds.
Hope this helps.
