Hey Satya.

See the marks u have scored is not that much enough for u to get admissioned in the good courses offered in the mechanical stream by the JNTU for pursuing ur higher studies. The only course u will be getting is ENGINEERING DESIGN.

U should be opting for other state colleges and private institutions for ur MTECH career. I m providing u a link for help.
