Hello student,
With a rank of around 12,000 in SC category, you can procure a seat only in your home state quota. You can get a seat in the following NIT's

• NIT srinagar
• NIT Goa
• NIT Surat
• NIT Puducherry

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. However you can predict the colleges which you are likely to get using the given link
