During this period, candidates must focus on subjects such as History, Geography, Polity, Economy, Ethics, Environment, Science & Tech, International Relations, Society, as well as both Hindi and English language papers, and Essay writing.

Since the Mains examination does not offer objective questions, aspirants must be able to present their thoughts clearly in writing.
