Dear Aspirant,

First of all it is quite difficult to make such predictions as it heavily depends on the number of students willing to take admission in the college and the seat matrix of the college.

A lot of students drop their seats in IISERs once they get offers from engineering or medical colleges.

There are 1700 seats in IISERs and about 1300 are reserved for IAT Candidates.

Looking at this we can say that you have a small chance of getting IISERs in the last or post allotment rounds . If you are passionate about science, please keep other options open.

We don't have any official cutoff information hence this is just a prediction based on the data I have given you.

Hope this helps.
