Approach for UPSC Mains GS3 (UPSC Strategy & Preparation)
Decode the UPSC mains syllabus into answer‑ready modules
- Convert broad heads (Economy/Agri/Env/Tech/Security/DM) into 30–35 mini‑topics with 2–3 model frameworks each.
- Maintain a one‑page sheet per mini‑topic: definitions, 3 data points, 2 committees/reports, 1 case.
Build a contemporary evidence kit
- Track Budget/Economic Survey, NITI/Ayog reports, flagship schemes, and 2–3 state innovations.
- Keep numbers handy: growth, logistics cost, RE share, air quality, insurance coverage, cyber incidents (credible sources only).
Answer‑writing method (for 150/250 words)
- Intro: definition/context (1–2 lines).
- Core: 3–4 sub‑points with micro‑headings (cause/impact/solution).
- Value‑add: 1 diagram/flow/box (max 15–20 sec to draw).
- Close: calibrated way forward (time‑bound, measurable, realistic).
