In order to get CSE at VIT University (assuming you are talking about UG courses), the closing rank is around 5K. If you score a rank under 5K, you'll have a chance in phase 1. As far as marks go, VITEEE has a concept of relative marking, meaning marking depends upon the number of students qualifying the exam and the relative performance of each student with respect to other students. 95+ will be pretty good score to get a rank of under 5000. Hope this helped. Good luck.

The difficulty level of VIT entrance exam is must lower as compared to jee main and other entrance exams. But CSE is one of the most demanding branch hence it's cutoffs are mostly very high. In order to get admission into CSE in phase 1 you need to aim for a rabk below 5k and for that you must have at leats more than 90-100 correct answers. 

Hope it helps.

Thank you.
