Dear Aspirant,
It is not possible to predict the exact admission 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 about 1300 seats reserved for IAT Candidates in IISERs and about 250 of them are reserved for OBC NCL candidates.
Looking at this data we can say that it is quite hard for you to get into IISERs. Please keep other options open .
These predictions are based on previous year trends and we don't have any official cutoff details from IISERs.
Please check the link below for more details.

Hope this helps.
