Hey Ajinkya,

At 90.29 percentile in JEE Mains, you CRL rank comes around 99333 - 111665 , which makes it very tough to secure a core branch at a good govt. college. Use the rank predictor tool:

As you have mentioned your category to be OBC. In JoSSA counselling you have little chance to get any colleges, but you can go for the CSAB counselling for lower branches in north-eastern NITs and some GFTIs if your preference branches are CSE and ECE, and if lucky you might get a seat in your home state NIT as well for a lower branch, but again this is not guaranteed and carries a lot of risk. Try the JEE Main college predictor:

Colleges such as BITS Pilani, MNNIT, LNMIIT have very low closing rank i.e., above 98th percentile for these branches. You can apply for state govt. college on basis of JEE Mains score, which can offer you CSE and ECE at your rank, so good luck with that.
