Hey Raghavan.

See the marks u have scored is not enough for to take admission in the top notch colleges like IITs and some of the NITs but it is enough for some of the NITs under ur OBC category. U can also apply for other state colleges and private institutions for ur MTECH career.

I m providing u a link for ur help.

Hello Raghavan

With this GATE score it will be difficult to get into IIT's especially the top 7. I don't think you can any IIT's. 

Now coming to the NIT's, You can get Allahabad, Shibpur, Surathkal(Maybe), Jamshedpur. You can also try the State Universities.
