Hello Bhagath Manickam

You will get a rank around 25,000. It will become difficult to procure a seat in the top NIT's. There are some NIT's which you may get if you belong to their correspondimg state like NIT Hamirpur, NIT Srinagar. Other NIT's have a close rank of around 6,000 in SC category. But, one thing to keep in mind is that scores and ranks vary each year with difficulty level of the question paper and availability of seats.

Hope this will Helpful

Good Luck.
