First of let me tell you one thing. In VITEEE examination there is not any type of cuttoff for class 12th examination. They just only check your class12 P.C.M percentage . It should be more than 60% and you rank should be under 1lakh inorder to take admission in various campuses of VIT. Only these are the two major factor during the time of counselling. 

If you are having more than 60% in P.C.M and rank is under 20k then you are in the safe zone to intake any of the desirable branch of any campus. 

Good luck
