83 marks in jee advance , obc ncl & 95.3 percentile in jee mains, 22900 obc ncl rank. what are possible IIT & NIT with courses

With 83 marks in JEE Advanced (OBC-NCL) and 95.3 percentile in JEE Main with ~22.9k OBC rank, your chances are roughly like this:

• In JEE Advanced, 83 marks is likely around the qualifying range for OBC-NCL this year.
• IIT chances are possible mainly in newer IITs or lower-demand branches.

Possible IIT options (not guaranteed, depends on cutoff trends & JoSAA rounds):

• Indian Institute of Technology Bhilai – Civil, Metallurgy, Data Science dual degree, Materials

• Indian Institute of Technology Jammu – Chemical, Civil, Materials

• Indian Institute of Technology Dharwad – Mechanical, Civil, Engineering Physics

Top IIT branches like CSE/ECE in old IITs are very unlikely at this score.

For NITs with 95.3 percentile + 22.9k OBC rank:
You actually have much better chances here.

Possible NITs:

• National Institute of Technology Raipur – Mechanical, Civil, Metallurgy, Mining

• National Institute of Technology Agartala – EEE, Mechanical, Production

• National Institute of Technology Silchar – Civil, Mechanical

• National Institute of Technology Srinagar – Electrical, Mechanical, Civil

• National Institute of Technology Jamshedpur – lower branches possible in later rounds

• National Institute of Technology Patna – Civil, Mechanical, Electrical (borderline)

IIIT chances:

• Indian Institute of Information Technology Una

• Indian Institute of Information Technology Kottayam

• Indian Institute of Information Technology Bhagalpur

• ECE/IT in some newer IIITs is possible.

Best realistic target:
• Mid/lower NITs with decent core branches
• Newer IIITs with ECE/IT
• New IITs only if Advanced cutoff stays favorable and counselling goes well
