Yes, for sure.
You don't even need to opt for dual degree course, you can get CSE in non-integrated course too, I guess.

Yes, one can opt for branch change in second year based on his/her score in first year but in the same college only. First year is common for all branches, transfer to another branch is not a problem. You can change the branch in any college but also check the college norms.

Hello Sanjeeb,
The fee structure varies from college to college. So, if you mention the name of the college with the exact course whether it is B.Tech computer science or B.Sc Computer science, then I may tell you.

Yeah definitely, I suggest a good college for CSE engineering, but before this information I am asking you to some questions like this which exam you face and what rank you got then I willing suggest you.
