Dear Akshita,
Cutoff marks and rank are vary from year to year and this year it is in the running process so we can't tell you the exact data for this year but according to previous year you can estimate your place.
If you try to come under the rank of 10K in VITEEE entrance exam then their is a very high chance that you will get CSE and for IT come under the rank of 15K for the safe side. Actually it s hard to estimate the cutoff by marks because VIT have never disclosed the marks they only show you the rank and if you are coming under that rank then definitely you can get CSE at main campus.
For more you can go through with this link to know the previous year cutoff of VITEEE for each campus. https://engineering.careers360.com/articles/viteee-cutoff
Best Of Luck!!!
