Well, borther it would be easier for to decide if you had told your category rank, your CRL rank.

But still from comparing from the rank vs percentile analysis, your CRL rank would be around 1.8Lac.

Well, owing to your category, you do have a chance of getting a seat at older NIT's or mideocre NIT's with decent branch.

NIT's you can consider are

1. NIT Durgapur

2. NIT Raipur

3. NIT Hamirpur

Thank You
