IIIT

.No, it is unlikely that you get computer Science branch in IIIT in any IIIT with 86 percentile in JEE Mains whether you belong to OBC NCl category.

You can check other colleges like NITs or GFTS, but it is unlikely that you get computer Science branch easily in those also 

Thank you

With an OBC NCL category rank of 1,51,000, it becomes quite challenging to secure a seat in the core branches of NITs or IIITs through JoSAA rounds. However, a few newer IIITs or GFTIs may still have openings in streams like Metallurgy, Production, or even Civil in later rounds. Keep an eye on spot round announcements and also consider private colleges with good reputations and lateral entry or transfer options in the second year.

With an OBC rank of 75,231, your chances of getting into a top-tier NIT, IIIT or GFTI are quite slim, especially in highly sought-after branches like Computer Science or Electronics. However, you might still have a slight chance in newer GFTIs or lesser-known IIITs with core branches like Civil or Mechanical Engineering under spot or special rounds. You may also explore state counselling opportunities in Tamil Nadu. Keep backup options ready in private colleges or deemed universities with scholarships to stay on track academically.

With a 72 percentile in JEE Main and belonging to the EWS category, getting into top NITs or IIITs may be challenging, but you might have a chance in newer or lower-ranked NITs/IIITs, especially under Home State quota and in less sought-after branches. It's advisable to participate in JoSAA counselling and also explore options through CSAB special rounds.

You might not get good NIT colleges and also good branch in NIT, you might have to take lower NIT and the branches will be like civil, chemical, environmental engineering

While for IIIT, you can try for IIIT Nagpur with lower branch, also, you can try. IIIT Ranchi. 

Yes, A 92 percent is a good score.Your chances of getting an admission depends on the programme you are aiming to join.To get admission in to high competitive branches like Computer Science engineering and Information technology, there mught not be much chance.Try applying for less competitive branches like Mechanical engineering, Civil engineering and Electrical engineering. 

Your JEE Mains ST category rank is 6690 so you would have quite a good opportunity in getting admission in different NITs, GFTIs and IIITs. Though the best departments in the best institutes may be hard, there are other reputed institutes that provide various type of engineering degrees in which you will have a chance to get an admission under JoSAA counseling. The advice is to be active during the counseling rounds and discuss all the possible options.

With an EWS rank of 59680, getting into IIITs like Guwahati, Kottayam, or Vadodara might be challenging since your rank is higher than their previous year's closing ranks. Explore other IIITs or consult with admissions offices for more information.
