What UPSC asks most

Constitutional provisions and the working of Parliament carry most questions: articles, procedures, powers of offices and recent amendments.

Most-asked topics in past papers: Constitution and Preamble, Parliament, Federalism and Centre–State Relations. See the trend

Traps to avoid

• Mixing up 'shall' and 'may' powers, and Union vs State roles.
• Statements that are true for Lok Sabha but not Rajya Sabha (or the reverse).

How to study it here

1. Read chapter by chapter in order; the Constitution builds on itself.
2. After each chapter, take its test and then its PYQs; Polity questions repeat ideas year after year.
3. Keep a one-page list of articles and schedules and revise it weekly.

Mains: GS II: link each chapter to a current debate (federalism, judiciary, elections).
