The most seniors and CSPs are hereby requested to tell me the strategy of answering History papers.

What i want simply is that History Papers like Indian History, European History, British History and Muslim History are different subjects from other subjects as they require a series of facts and figures, What pattern to be applied answering a question? How to present the facts and figures and What should be the Format of an answer?
I would appreciate if querry is supported with a brief History question and answer.
