You will not get it even you will not be able to take part in counselling too.So try for some other entrance exam.Jee main and other state entrance.There may be some category.But with this rank no chances

my rank is 69651  . can get a seat in any of the branch in vit chennai ??

With this score the chances are less for VIT Vellore & Chennai to get ECE branch. But The chances are there VIT Amaravati & VIT Bhopal Campus. I would suggest you to check your best possibilities based on your score with VITEEE college predictor tool given below.
