Hello,

Amrita University accepts JEE Mains scores.  In the FAQ section of their official website, it is mentioned "It is not correct for us to predict a minimum rank requirement for admissions into various campuses of Amrita School of Engineering. Ranks keep varying year on year.
You will be allotted to some other campuses if there are vacancies.
At the time of Seat allotment, you will be asked to select the Course preference and campus from our all campuses. Based on that you will be allotted seat. "

To predict the colleges that you will get through JEE Mains, you can use the college predictor tool:

Hope this helps.
