Dea Raghu Venkat,
No, its really typical to get admission in any branch with such rank in VITEEE. However, to get admission in your desired branch, the cut-off rank will vary considerably.
you needs to get rank under 10K.

This is the course fee for the year, and you have to pay this fees every year. It is not dependent that whether you have cleared the VITEEE or not.
It is college fees which you have to submit throughout the year.

Actual cut-off is not declared but first 20K will be called for in next month. But obviously, CSE is the most sought after branch and hence closing rank is very tough. Last year, it was 7000. Best wishes.

VITEEE is comparatively easy because it does not need you to have that much deep knowledge. It has English, Maths, physics, chemistry, and logical reasoning as well with no negative marking which makes it easy for every other participant too.:Physics questions were very easy. Most of them were just informative questions with little or no calculations. Chemistry was much easier than previous years and the questions were blindly picked up from NCERT. Maths was a bit lengthy and tough.
