Dear aspirant

It would have been good if you have mentioned your all india rank.

Although your category rank is quite good and some time you may have chances as total approximately seat in IISER is 1700+ and 50% are for Gen category students so by comparing this you have chances to get any of one IISER through this rank.

Last year IISER was allotted upto AIR 9050 in EWS category. So your all india rank is below than this you might have good chances to get IISER college.

Hope this information helps you

All the best
