Hello Sonali,

You are talking about Aviation Management right. If yes then this is the process. 

Aviation Management needs minimum 50% marks in any discipline but preferablyy in economics or commerce background mathematics, with minimum 2 years of experience in an aviation or any sector releated to this. If you have this then you have to give entrance exams likes CAT, MAT,GMAT OR KMAT. And you will be selected into any of the top insitutions.

Hope this helps

Good luck
