I am also scoring exacty same marks. I don't think there is a chance unless or until you are of reserved catogry( Sc or St or Obc)

Hello aspirant,

As IISER cutoff marks have their own criteria to select the students. Cutoff marks can be depends on different school boards such as CBSE, ICSE and Other state boards. Cutoff list mentions the minimum required score by the applicants out of 500 in class 12th. Also cutoff lists depends upon the different categories like GEN/EWS, OBC,SC/ST and PwD.

If you belong to CBSE board and you are in general category then you should score 427 marks, if you belong to OBC then score should be 416 marks, if you are SC/ST then 376-396 marks.

And you scored 68 marks so chances seems to be less to get any IISER.
