Overview: Are you tackling the voluminous syllabus of the UPSC Civil Services Examination (CSE) Law Optional subject? If you want to transform your preparation from theory-heavy to score-heavy, then dive into the indispensable revision techniques explicitly tailored for UPSC Law Optional aspirants.
Law is often considered simple and easy to understand because of the wealth of available reading material. However, mastering this subject, which spans everything from Constitutional governance to International treaties and contemporary legal issues, requires more than just reading; it demands smart revision.

The UPSC Law Optional subject consists of two papers, each carrying 250 marks. The subject is structured to evaluate candidates ’ grasp of key legal principles, interpretative abilities, and their application in real-life contexts.
The syllabus is systematically categorised into two papers, focusing on foundational/public law (Paper I) and substantive/private/contemporary law (Paper II).
| Optional Paper | Broad Topics Covered | Key Focus Areas |
|---|---|---|
