Hi

It depends on which exam you are applying for. You haven't specified the examination name.

To tell you the actual meaning of ' subjects concerned ' it generally refers to a subject whose marks the testing agency considers and is a eligibility criteria. It basically means the subjects which are related to the examinations for admission in UG courses of science after 12th standard exam .For example in NEET marks of biology is considered and without biology Biotechnology marks is considered, so Biotechnology becomes the subject concerned. There the some exams where English marks is considered along with physics, chemistry and maths. The English here is a subject concerned.

Hope this helps.
