Dear aspirant,

It is quite difficult to predict the exact situation as it depends on the number of students willing to take

admissiointo the college and the seat matrix of the college.

There are 1700 seats in 1ISERs and about 1300 are reserved for candidates entering via the IAT examination. Looking at this trends we can say that you have a good chance of getting into IISER.  You can get Tirupath, Berhampur in later rounds. You have a small chance of getting TVM/Mohali in the last/post allotment rounds.

Usually, all students who have attempted IAT might not accept the admission and some might leave after getting admission as well. We don't have any official cut-off details and hence these are just predictions based on what the students had informed.

Hope this helps.
