Hey Swaroop.

See u are from one of the core stream in the engineering discipline which itself creates a huge competition. The score u have scored if enough for u to get qualified in the GATE exam but it might not be sufficient for u to get admissioned in the good NITs and IITs for pursuing ur further studies.

U should be opting other good colleges like DELHI UNIVERSITY or other good colleges which accept the average marks for pursuing the higher studies.

Hope it helped u. Ask me if u have any query.

Good luck
