hey,

since you  got 64809 tank in vit exam of 2020 . I don't think that you get Vellore or Chennai campus for CSE or ECE in first slot. However you can get these branches at Bhopal And Amravati Campus.

Preferred is Bhopal Campus than Amravati for the same.

However you can get Vellore or Chennai campus by some other branch.

Thanks and regards
