even my first language is not english,it's not the language matters the technique and the way you present the answers. when looking at EO it's full of scenario and practical application based on the question.

eg: how to apply diamond theory in a given context,you shoul read the scenario and understand the requirement,and then develop an answer paln based on that. the you will talk about the demand conditions ,factor conditions,related and supportive industry and industry rivalry and strategic frame work and its importance to gain a competitive advantage.always remember dont missout the scenario always try to relate the theory,then u will get marks 

Hi, I think I yet got an answer. anyway I was talking about an  scenario given.
