Hello Shivkumar

If you are expecting a score of 705 and that too having a OBc reservation then in almost all the NIT's you can get shorlisted.

You can even get a call form Roorkee IIt, yes i know chances are less but who knows may be you can get into IIt Roorkee.

The top NIt's in which you can get are : NIT R, NIT Surathkal, NIT W, NIT T.

For specialization, please opt for Control as it is high in demand, you can also opt for PE.
