Hello Surya.

See the marks u have scored is enough for u to get admissioned in the good colleges like NITs or IITs for pursuing ur further studies in any of the round. Since the cut off of the colleges start from 65 marks for general category.

Moreover ur branch is one of the core branch in the engineering discipline which itself creates a huge competition. U can apply for other state colleges or private colleges for pursuing higher studies.

Hope this helped in some way. Ask me if u are having any query.

Good luck
