3. Link with Current Affairs: Whenever an article is in the news (e.g., Article 356 during President’s Rule, Article 21 for Right to Privacy), revisit it in your notes and understand its contemporary relevance and recent interpretations.
4. Focus on Amendments: Understand how major Constitutional Amendments have impacted or introduced specific articles.
5. PYQ Analysis: Go through Previous Year Questions (PYQs) for both Prelims and Mains. This will clearly show you which articles are frequently tested and in what context.
6. Judicial Pronouncements: For Articles like 21, 14, 19, 32, link them with important Supreme Court judgments (e.g., Kesavananda Bharati case for Basic Structure, Maneka Gandhi case for Article 21’s expansion).
7. Regular Revision: Polity is highly factual. Consistent and spaced revision of these articles and their implications is paramount for long-term retention.
