Hi Kiranmai.

As your rank is 31158, if you're General, you can geta seat in NIT-AP. If you're applying in HS quota, you can get Chem., Civil, Bio Tech. and Metallurgy. In OS quota, you can get Civil, Bio Tech. and Metallurgy.

In the case of NIT Puducherry, you won't get any seat under OS quota. Under HS quota, you can get any of the course.

This is for General category, and it will be different for other categories. You can check the cutoff here.
