Hello!

Please be clear with the fact that no cutoff score or rank is released by the IISERs. It is just the assumptions by the candidates that surface after the IAT examination after the answer keys are released.

In that context, for general category about 90+ was required to score in IAT for at least securing a seat in their second preferred IISER(in the 1st or 2nd round of allotment) and about 80+ for their third or fourth preference (after third round of allotment).

For OBC-NCL and other reserved categories about 80+ marks made their 1st or 2nd preffered IISER for them in 2019. About 70+ marks will be required to secure a seat in the newsest IISERs(Bpr and Tirupati). In the last rounds of allotment, general category students with 75+ marks got BS economics and engineering studies in IISER Bhopal.

So it is difficult to say what was the base marks in 2019 to get an IISER because they are just assumptions.

Anyway, be patient till the last rounds of allotment if you are in a hope of scoring 75 and above.

All the best!
