JEE Advanced

Yes, you can. But, it depends on the other students of your category. I will suggest you to wait for the spot round or last round. You may get lower branches.

You can check Central University of Karnataka. It accepts jEE Advanced score. Most of the colleges accept JEE Mains marks and ranks to admit students in B.Tech.

No, you must have to take JEEADV, and if I am not wrong, you should score minimum 20% marks in JEEADV to get shortlisted for selection. Though with that percentage, it may not be possible for you to get a seat. You should go through the admission guidelines of IIST for clarification.

Hello Shashank,
No, it will be not considered by rounding off, you need a proper 75% marks to get admission in any IIITs, however, your rank will be shown up but you will not get admission.

It is quite tough to get it as your JEE Advanced rank is too low but don't worry, just check the closing rank of different IITs by this link:

Quite tough to get IITs but please check the closing rank of different IITs by josaa according to category:

You have to score more than 10% in each subject in JEE advance exam and more than 35% marks are required to qualify the JEE Advanced exam hope you got this marks and qualified the exam as results are declared today.

Hello Gaurav,
If your JEE Advanced hall ticket is available then definitely appear for the exam, there would have been some error but you can clear that out by contacting any of the admission officials.
