While setting up your preference you should keep the factors in mind such as best academics, infrastructure, placements & faculties. Now AVVU's have all of its campus well oriented but considering the upper parameters, you can set this as a preference order:

1. COIMBATORE (Ettimadai ) CAMPUS
2. BANGALORE CAMPUS
3. AMRITAPURI CAMPUS
