Dear Aspirant,

IISER does not release their cutoff at all so it is nearly impossible to predict the cutoffs for the universities. All you can do is just give your best during the examination. You need to be a KVPY scholar to get admission in IISER through KVPY channel. You need to have JEE Advanced rank below 10000 to apply for IISERs through JEE Advanced channel. And there is no definite cutoff for SCB channel. They just release the list of candidates who qualified.

Hope this helps. Good Luck!
