Hello,

As your rank in VIT is not that good i would say not to opt for it. However you can get cse specialisations in category 3 and there is a good chance to change your branch in 2nd year.

I would suggest you to go for comedk colleges as you have a good rank there and can take up cse branch there even if you don't get in the top 5 colleges because the cost in course four years of B.tech is less in the Bangalore colleges rather than VIT Vellore and SRM University.
