Integrating political theories into UPSC exam answers requires a thorough understanding of key doctrines like Liberalism, Marxism, and Feminism. Candidates should reference these theories when applicable to current events, policies, or historical contexts in their answers. Structuring answers with a distinct introduction, application of theory, and a critical evaluation enhances the quality of responses. Use specific examples from Indian politics to demonstrate the practical relevance of these theories. Finally, practice writing concise answers to ensure clarity and depth within time constraints during the exam.
