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, the seat matrix of the colleges and the number of students willing to take admission.

A minimum of 1300 seats are reserved in IISER for the candidates via IAT. Looking at this trend we can say that it is quite difficult to get into IISER with this rank. In my opinion a rank below 5 K is a safe estimate.

Hence, please keep other options open as well.

You have a small chance of getting least preferred IISERs like Berhampur in the last or post allotment rounds as people leave after accepting the seats as well.

Hope this helps.
