Dear Amit

There is no category based system in VITMEE as far as I know. Your rank is 386 which is quite good and with this you can get any branch of your choice which being cad/can in your case . You can get it in VIT vellore which is the main campus and is one of the best colleges in India. So I would suggest that you keep a check on start of counselling and fill your choices accordingly.  I wish you luck.
