You won't get the best college but may get a decent college with non-core branches. I would suggest you work hard for your 4 years to get success in your life. Visit Shiksha's college predictor to get better exposure on colleges and branches.

It is quite difficult to takw admission in any of the college for M.Tech without appearing for any of thw entrance exam. But still there are some hopes, you can approach some of the Deemed university.

I will prefer IPES. It placements are good as comparison to others. And study is also well mannered.
