With 157 marks in JEE Mains, your percentile will be around 96–97, and your rank around 35,000–40,000.

As an OBC-NCL female candidate, it’s very unlikely to get CSE at NIT Trichy, where CSE closes under 2,200 rank (OS quota).

However, you may get CSE in newer NITs like NIT Puducherry, Sikkim, or Arunachal.

You can also try other branches at NIT Trichy like EEE or ECE.
