Greetings of the day Aryan

First of all, congrats for successfully completing VITEEE exam. We know that VIT doesnt release it's official cut-off's, but we can just predict it based on the previous year trends. So with a rank of 30,000, comparing with available previous year data, you have chances of getting these branches :

Civil Engineering (Vellore Campus)

BioMedical Engineering (Vellore Campus)

Production and Industrial Engineering (Vellore Campus)

Mechanical, Civil, Fashion Technology, Electronics and Computer Engineering (Chennai Campus)

But don't lose hope. Participate in the counselling process. Cut-off's happen to change every year. It depends on a variety of factors such as number of students attempting the exam, difficulty level, available seats, etc.
