Hello,

As the counseling process of IISER is about to start now, they launch the website for registration, going with JEE Advanced channel or their own aptitude test, they update seat allotment results after every round in the site. In the site, you create a profile for registration and fill your choices, it is in your profile, you get to know if you have got any seat in any IISER. https://www.iiseradmission.in/apply/ go through this site for registration, counselling will be starting soon.
