My friend recently got into vit Vellore in artificial intelligence!
He applied in all vit's he also has been selected in vit bhimavaram! I asked him about the cutoff once he said for ai the cutoff is near about 7300! You can do ai if you are under this rank! And depending on your rank there are categories. If you are in category 1 you have to pay low fees and if you fall under category 3 or 4 you have to pay more fees to get admission there. Depending on your rank fee may vary!
All the best for your career. Regards
