Hey Jhagan

IISER Pune has a cutoff of around 105 to 11o for general category but the rest of the IISERs have a closing rank somewhat around 75 to 80. Due to the corona virus nd lockdown the cutoffs are expected to vary but no one can say for sure whether it will decrease or increase. IISER does not release any cutoff but only tells the applicant whether he is selected or not hence it is impossible to predict anything at this stage.

All that being said I think your score is enough for your category to get you a seat at IISER Thirupati but you will have to stick till the end. All the best!
