l score 21 marks in iiser exam and 80% in +2 exam can I selected in iiser??? catagory (SC)
Hello Ashish !
Though there is no official release of cutoff marks or rank by the IISERs, but it is generalised that at least 70+ marks is required for reserved seats in the newest IISERs.
It is very unlikely for you to get any IISER with 21 marks in IAT. Please note that your board % doesn't play a great role for getting you in the merit list because you just have to cross the cutoff for SCB to appear IAT.(i.e 60% for all boards this year)
There is another chance for you in the next year.
All the best!
