Do you think Operation Research is a difficult subject?

Any subject is not difficult if you are keen to learn and devote time and energy.

In my point of view,anyone who has interest in particular thing won't find it difficult.

Operational Research is highly celebral and a demanding field as the very nomenclature suggests it involves indepth study of complex opeartions and processes of any organization. To my knowledge it demands mathematical applications of higher standards and persons possessing advanced knowledge in mathematics can think of pursuing this.
