Hi Gaurang Krishna !

Due to the COVID-19 crisis this year, the SCB cutoff for state and central boards were relaxed to 60% (not top 20 percentile anymore).

So the marks secured in your boards doesn't matter unless it is less than 60%.

Now coming to the fact that you secured 75/180 in IAT test. If you belong to general category, it is difficult to predict....because gen-EWS category reservation is introduced this year so cutoff may vary greatly.

Also it depends on your list of preferences if you will bag a seat. If you have IISER bpr or Tirupati in the first or second preference then you may get them in the last rounds of allotment.

Still I request you to wait till the last rounds of allotment...there may be post allotment sessions also..keep checking your emails and stay updated.

All the best !
