Hello Priyajit. You mentioned you belong to GEN-EWS category and that you want to know whether you may get admission in IISER, Kolkata on the basis of your JEE Advanced result.

Indian Institute of Science Education and Research (IISER) intakes applicants on the basis of either of the three channels/mediums -

• SCB Channel - based on 10+2 board results + result of IISER Aptitude Test
• KVPY Channel - based on 10+2 board results + valid KVPY fellowship
• JEE Advanced Channel - based on 10+2 board results + JEE Advanced result.

General category candidates must secure an Overall AIR within 10000 in the Common Rank List (CRL) of JEE Advanced 2021 while the Category Rank of Reserved Category candidates (OBC-NCL, SC, ST, PwD), should be within 10000.

You mentioned your CRL-AIR is 9682 as well as your Category Rank is 1157. You should worry less as you are going to have good window of opportunity to get admission at any branch of IISER (including IISER Kolkata).
