Hello

I am sorry Amrita does not give you details like how the marks.

The ranks change every year deepending on the number of students and the difficulty of the question paper. It just gives you your rank and their admission is dependent on the rank secured by you in AEEE or JEE( it is also merit based) and also on the campus that you have selected. For more details you can visit https://www.amrita.edu/admissions/btech-2020/faq . All the best.
