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 1300 seats in IISER reserved for IAT Candidates and about 200 seats are reserved for students of each category (apart from general).
We don't have any official cutoff details from the college and hence these predictions are based on experiences only.
Based on the given statistics we can say that it is quite hard for you to get into IISERs. If you are passionate about Science please keep other options open.
Please check the link below for more details.
IISER cut-off
Hope this helps.
