Overview: Choosing the right optional subject is arguably one of the most critical decisions an aspirant makes during their UPSC Civil Services Exam (CSE) preparation. With 48 optional subjects available, finding one that aligns with your strengths and maximizes your score potential is paramount.
If you are seeking a subject with a stable syllabus, significant General Studies (GS) overlap, and inherent clarity in structure, the Law Optional subject stands out as a highly strategic choice.
A strong performance in this optional, which carries a weightage of 500 marks in the UPSC Mains Exam, can significantly bolster your overall score and improve your chances of reaching the interview stage.
Law is generally considered a good optional for UPSC due to its scoring potential and synergy with other parts of the examination. It is typically thought of as being simple and easy to understand.

|---|---|
| GS Paper II (Polity & Governance) | Paper I, particularly Constitutional and Administrative Law, aligns closely with Governance and Polity. This includes topics like Fundamental Rights, Directive Principles, the Constitutional position of the President and Governor, Emergency provisions, and Administrative tribunals. |
| GS Paper III (Technology & Environment) | Portions of Paper II, specifically the Contemporary Legal Developments section, overlap with GS Paper III. This includes topics such as Information Technology Law (Cyber Laws) and major statutes concerning environmental law. |
| Essay and Interview | A strong understanding of the Law syllabus is beneficial for enhancing performance in both the Essay paper and the UPSC interview. |

Familiarity with the main topics covered in the syllabus reduces the overall preparation time required. The syllabus tests not just theoretical knowledge but also the application of principles in practical situations.

| Optional Paper | Focus Areas | Key Topics (Broadly) | Marks |

| Paper I | Foundational & Public Law | Constitutional Law (e.g., Fundamental Rights, Judicial Review, Amendment), Administrative Law (e.g., Natural Justice, Delegated Legislation), and International Law (e.g., Law of the Sea, UN, Treaties). | 250 |
| Paper II | Substantive Laws & Contemporary Issues | Law of Crimes (e.g., mens rea, Offences against Women/Property), Law of Torts (e.g., Absolute Liability, Consumer Protection Act), Law of Contracts & Mercantile Law (e.g., Partnership, Negotiable Instruments), and Contemporary Legal Developments (e.g., PIL, IPR, Cyber Laws). | 250 |
