Hello dear aspirant

At first, I would like to congratulate you on successful completion of your VITEEE exam. The cut-off trends keeps changing every year and it depends on the number of students attempting the exam, difficulty level, number of available seats, etc. With a rank near to 29,000, you cannot get a Bio Technology seat in Vellore campus in any fee category as the cut-off for the same was 13,500 in 2015 and 20,000 in 2016. You can try applying for Bio Technology seat in any of their other campus where you can easily secure a the seat or any other seat in 1st fee category itself.
