Hey, first of all you not define which board you belong from so I assume as cbse board. Amrita university  was come under ranked 4 by NIRF 2020 .Amritea university admission is based on JEE Mains or AEEE rank.

To get Scholarship from Amrita university you have to write entrance exam as I mansion AEEE in which also you want to secure good rank under 2K something to get any type of scholarship.

But you have good chances to get seats through your JEE Mains score in Amrita Universities.

All the best!!
