Hello student!
As per the COVID-19 pandemic, the IISERs have relaxed the state and central board cutoffs to be eligible to apply for the IAT 2020.
The cut-off marks in 10+2 as eligibility for IISER Admissions 2020 is modified as follows: either 60% marks in aggregate or equivalent grade for General/ OBC and OBC-NCL categories and 55% for SC/ST/PWD in any boards or the cut-off marks already announced for each of the boards in the admission website, whichever is lower.
So, as you have scored 55% in your boards being a PWD candidate, you are eligible to sit for the IAT test.
You have to score above 90 in the IAT test to get your first three preffered IISERs easily in the forst or second rounds of allotment. Anywhere above 75+ will get you a seat in your 4th or 5th preferred IISER.
