How do I identify high-yield UPSC topics?

Sort PYQs by frequency (most repeated first) and mark-weight (15-mark questions matter more than 10-mark). Topics asked 5+ times in 12 years have 60-70% probability of reappearing. UPSC repeats themes, not exact questions — master concepts not memorization.

Should I solve all UPSC PYQs?

Yes — solving last 10 years of PYQs (twice) is the highest-ROI Mains preparation. Identifies UPSC's question patterns, vocabulary, depth expectations. Better than reading 5 books superficially.

How to Use PYQ Frequency Data

🎯 Why PYQ Analysis Matters

UPSC repeats themes, not exact questions. A topic asked 3+ times in 10 years has 60-70% chance of reappearing.
Time is finite. Studying every minor topic equally is inefficient — high-frequency topics deserve 2-3x the prep time.
Anudeep Durishetty's strategy: Solve PYQs first, identify patterns, then read NCERTs/standard books with PYQ lens.
Mains is selective: UPSC has ~20 high-yield themes per GS paper. Master these, you're 70% ready.

📋 Using This Tool

Filter by paper — see GS3-specific high-yield topics (Economy, Environment, Science).
Sort by mark-weight — a topic asked 3 times with 15-mark questions yields more than 5 times at 10 marks.
Click subtopics to drill down — within a broad topic, certain subtopics dominate.
Compare with current affairs — high-frequency topics that match recent news = highest probability for current year.

⚠️ Don't Over-Optimize

Cover the syllabus first, THEN use this data to prioritize revision and depth.
Low-frequency topics still appear — never zero out anything entirely.
UPSC changes patterns sometimes. New areas can emerge (e.g., AI ethics, data privacy).
Quality > quantity: 5 deep, well-revised topics beat 30 superficial ones.

Frequently Asked Questions

How is "frequency" calculated?

Frequency = number of times a topic appears in UPSC Mains questions across GS1-4 (2013-2024). Topics are normalized using the categorization in our PYQ database. A topic asked 5 times in 10 years has frequency 5.

What does "mark-weighted" sorting mean?

UPSC asks both 10-mark (150-word) and 15-mark (250-word) questions. Mark-weighted sorting multiplies count by marks-per-question to give higher priority to topics asked at 15 marks (which require deeper preparation).

Where does this data come from?

BharatNotes maintains a manually-curated database of all UPSC Mains questions from 2013-2024 (GS1, GS2, GS3, GS4 papers). Each question is tagged with topic and subtopic based on UPSC syllabus mapping. Browse the full database at /mains/pyq/.

Does this include Prelims PYQs?

No — this tool focuses on Mains only because Mains topics are more strategic (you need depth, not just recognition). For Prelims PYQ stats, see our PYQ Stats & Analysis page.

Are 2024 questions included?

Yes — the database includes UPSC Mains 2024 questions (held September 2024, results December 2024). 2025 Mains will be added after the exam is conducted.
