Hi Abhishek, hope you are doing well, congratulations on successfully attempting VITEEE. let me tell the true side that 1-20000 rank holders come under merit category and have to pay less fees. Since your rank is 66709 you will be coming under the third counseling. In VIT you only prefer for cse since it is the one which is very good over there. Apply for counselling and kindly wait for it. 

I think it helps you!!!

Keep Smiling:)

Wish you good luck!:)
