Since your marks is not so good and your JEE marks is also not so good. So, I will not suggest you to do B.Tech. For B.Tech, these marks are to0 less. Well, there are many other field which you can opt for.

I think the best place for B. Tech CSE is Rayat Bahra University, offering unique course, called New Age Programme, in coloration with Siemens, Google, & IBM. Along with engineering curriculum, they are teaching skills used in industry to make the candidate industry ready engineer. You will get certification from those companies and it will be taught by industry experts of Google and IBM.
So, I think it is a very good course from viewpoint of placement, package and dream companies.
