IIIT

With JEE Mains rank 32255 and belonging to SC category there are less chances for getting any IIITs because of their high cutoffs but you may have chance to get into low cutoff IIITs like IIITs Bhagalpur, Kottayam, Ranchi, and Nagpur but you won't get Computer Science Engineering branch into IIITs. For NITs you may get NITs with low cutoff ranks like NIT Patna, NIT Durgapur, NIT Mizoram, NIT Sikkim, NIT Raipur and NIT Goa.

No, it is not possible to get admission in IIT or IIIT or DTU from the 2nd year of BTech CSE. These institution does not give entry in 2nd year. You have to follow the process of admission from the first year only.

It is not likely that you can get admission in NIT or IIIT with 92.4 percentile with the rank of 112416 and 36416 OBC category. You may get any other government college of Bihar but it is not likely that you get an IIIT. Kindly look for another colleges.

With 55 percentile, 691000 CRL and 55000 rank in SC category in JEE Mains it is tough to get admission in NIT or 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.

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.
