Hi Mohnish,  

   The chances of obtaining a seat in Bannari Amman Institute is fairly possible. But according to the  last year cut off in that particular college it seems to be less possible only. But do not leave your hope and confidence and also apply for other colleges in the city to increase your chances to obtain a seat in a good college and pursue your MBA study.
