Dear Diya Roy,

Yes, you have good chances of getting B. Tech  Computer Science Engineering in Vellore Institute of Technology based on previous year's cut-offs. As your Rank falls under previous year's cut-off ranks. For you Computer Science Engineering Specialization in Information Security would be better and even you have good chances of getting this branch also. The cut-offs varies from campus to campus and branch to branch. The cut-offs will depend on factors like number of students appeared, number of seats available, category, difficulty level of the exam, etc.

For more information about VITEEE cut-offs go through below link.

All The Best!!
