Hello Siddharth,

Since IISER does not declare their cutoffs, it is difficult to tell whether or not you get admission they just tell whether or not you were selected. However according to past students personal experiences cutoff of about 110/180 marks is generally required to get into any IISER. It is unlikely you will get selected. However, this is just an assumption.

Hope that helps and feel free to ask if you have any more queries. Best of luck!
