Hello Prem

For calculating the aggregate marks and cut-off marks for fulfilling the top 20 percentile criterion, the following 5 subjects will be considered:

(a) Physics
(b) Chemistry
(c) Mathematics
(d) A Language
(e) Any subject (other than four above mentioned subject).

This means you can add any subject.But keep English as mandatory,which increases the scope of getting admission

Hope this helps you

Thank you!!
