Hi Aspirant,

Hope you are doing great as per the question asked by you as you have secured air  1683 and obc 647 in N.I.M.C.E.T so getting any N.I.T in spot round is very difficult as you have secured very high rank as compared to seats as you need to achieve rank around A.I.R 800- 900. So you should try next year with hard work and should try to achieve high and high.

Hope you found this answer useful.Stay motivated stay positive.

All the best!
