Sorry to say but with this rank you wouldn't be able to get CSE at least in the main campuses like vellore and chennai however you might get a seat in VIT bhopal or AP as because of being new there cut offs are very low as compared to other branches of VIT so you can attend the councelling of VIT and side by side i think you should also prepaper for jee advance and try to score good in that but make sure that the councelling fee of VIT isn't returned if you once attended the councelling so if you are sure about you jee advance score you may even skip VIT.

Good Luck!!
