500 Mains marks
UPSC Optional Subjects
Optional is two papers and a large share of Mains marks. Choose once, then finish the syllabus. Do not shop subjects every month.

In short: The UPSC Optional is two Mains papers (500 marks in the recent scheme). Pick a subject from the official list using overlap with GS, availability of teachers and PYQs, and whether you can write for three hours. Law Optional suits candidates who can read statutes and case method, not anyone who “likes debating.” Confirm the list in the latest notification.
How to choose without gossip
- Read the official syllabus PDF for two shortlisted subjects
- Attempt one PYQ paper each under time
- Check whether you can get evaluated copies
- Prefer overlap with GS (e.g. PSIR, Geography, Anthropology, Law for some GS-II/IV themes) only if you will still finish optional itself
Law Optional in brief
Law Optional rewards candidates who already think in issues, facts, and holdings. Paper coverage typically includes constitutional law, international law, crime, tort, contract and related jurisprudence as notified. If you are also preparing CLAT-style entrance exams, that is a different paper — use the Law Resource Centre for entrance PYQs, not as a substitute for the UPSC Law Optional syllabus.
When to start Optional
After a first GS loop is moving, unless you are a repeat candidate with a locked subject. Starting optional in week one without GS often delays Prelims. See the study plan.
FAQs
Which optional is the most scoring?
There is no permanently “safest” optional. Marks move with the paper and the candidate. Choose a subject you can complete and write well.
Is Law a good optional for UPSC?
It is good if you can handle statutory language and case-based answers. It is a poor default for candidates who only want GS overlap. Read the official Law Optional syllabus before you decide.
Do you host Optional PYQ PDFs?
Not in this library. Use the official UPSC archive for your subject. We host Essay and GS I–IV.
Can I change optional after Prelims?
You can, but you burn the year. Lock the subject once you have tested it with a PYQ paper.
