Hello Krishna,

As you have mentioned above that you have scored 550 in the GATE examination, in General Category, there is a slightly fair possibility that you would call from IIT's and PSU's.

I would recommend to make a list of IIT's and PSU's you want to apply to and email them your score.

And for the further details, if you have any query you can even visit our website, where there is a detailed description which would be quite helpful for you
