Hello dear aspirant

At first, I would like to congratulate you for successful completion of the VITEEE exam with flying colours. Getting CSE seats is becoming really tough as they have high demand these days. Also, the cut-off trends is unpredictable and changes every year based on the number of students attempting the exam, difficulty level of the exam, number of seats available, etc. With a rank of 12000, you may secure a CSE seat in Vellore campus in 4th or 5th category as the cut-off was 7000 in the year 2016. It's really hard to get a seat in last 2 categories too. So, just apply to their counselling process and get to know the exact category as its really hard to predict this year's cut-off.
