Mechanical Engineering

Hello Puneeth,
If you want to pursue your Masters abroad and that too in English speaking country then you can do so in US, Canada, Australia, England,etc. I think other countries may have but you should restrict to these four only.

Yes, with this rank, you will get a good college like:
Jalpaiguri Government Engineering College for Mechanical Engineering
You should go with mechanical, rather than IT. There are lots of opportunities in mechanical.

Choosing any stream in engineering should be your personal choice and interest. Both the branches are different. I think you should choose electronics and communication.

DCRUST and YMCA Faridabad.

It is not a very well known engineering college in the country or in the state or in the city. This is mainly because it is being recently started. The faculty in the departments are pretty decent but not very great. I have heard that focus on research is good in some departments like mechanical and automobile, but is really bad in some core departments like Electrical. Placements are not that great.

You should score near about 250 for CSE, 220 for mechanical and 200 for electrical.
