12-Month Study Plan (Oct 2025 ? Sep 2026)
Phase 1 — Foundations (Oct–Dec 2025)
- Revise micro & macro basics; start a formula & diagram register
- Begin Indian Economy timeline notes (decade-wise highlights)
- English: weekly essay + précis; GS: concise current affairs mapping
- Econometrics warm-up: OLS intuition, assumptions, classical issues
Phase 2 — Core Build (Jan–Apr 2026)
- Paper III–V heavy lifting: problem sets every alternate day
- Public finance + international economics integrated with news
- Indian Economy: sectoral sheets (agri, industry, services, finance, external)
- Start PYQs topic-wise; make “trap notebook” of frequently tested pitfalls
Phase 3 — Consolidation & Mocks (May–Jul 2026)
- Sectional tests begin; two full-lengths/month
- Indian Economy answer-writing with data points & policy chronology
- Econometrics: inference language practice—what does ? mean in policy terms?
Phase 4 — Peak & Polish (Aug–Sep 2026)
- 12–16 full-length mocks overall; strict time discipline
- Two revision cycles; compress notes to last-week packs
- Weak-link clinics: whichever chapter or method still feels clunky
PYQ Method & Topic Mapping
- Classify past 10–12 years by paper ? topic ? sub-topic (e.g., micro: monopoly, welfare, GE; econometrics: OLS, heteroskedasticity, IV).
- Mark verbs in questions: “derive,” “prove,” “show,” “discuss,” “critically examine,” “evaluate policy impact.” Each verb demands a different structure.
- Write condensed key solutions (1–1.5 pages): diagram + 2–3 core steps + brief policy link.
- Track recurrences: topics that appear 3+ times deserve mastery + ready-to-write frameworks.
Convert PYQs into templates—for instance, in macro “inflation” or “exchange rate” answers, keep a ready scaffold: definitions ? mechanism ? diagram/math ? evidence/data ? policy trade-offs.
Econometrics & Quant Tips
| Theme | Must-know | Exam-ready Output |
|---|---|---|
| Classical OLS | Gauss–Markov assumptions; BLUE; consequences of violation | 1-para explanation + 2 equations + tiny diagram if relevant |
| Diagnostics | Heteroskedasticity, multicollinearity, autocorrelation tests | State test, null, remedy (White/robust SEs, VIF intuition, DW) |
| IV/2SLS | Endogeneity, instrument relevance/exogeneity | One real-world policy example (e.g., education returns) |
| Time-Series | Stationarity, unit roots, ARMA intuition | Meaningful interpretation > formula dump |
| Panels | FE vs RE intuition; when to use which | 1 diagram of within/between variation; Hausman idea |
Language matters: Examiners reward clear interpretation of coefficients, assumptions, and limitations. Be precise, not verbose.
Answer-Writing Framework (Economics Papers)
Use a consistent, examiner-friendly structure:
- Intro: Define core concept; state the crux.
- Body A — Theory/Derivation: Diagram or math with crisp steps & intuition.
- Body B — Application: Indian/real-world linkage; recent policy/data.
- Body C — Caveats: Assumptions, limitations, competing views.
- Conclusion: Balanced 2–3 lines; policy implication or way forward.
Don’t: dump formulas, write generic essays in technical papers, or ignore diagrams. Marks follow structure + clarity + application.
Mock Tests: Volume, Analysis, Error Logs
- Volume: 12–16 full-lengths (all papers), 8–12 sectionals (III–VI heavy)
- Post-mortem: For each mock, note 10 takeaways: 4 concept gaps, 3 structuring issues, 3 speed/choice problems
- Error log: A running sheet with: concept & page ref ? fix ? mnemonic/diagram ? revisit date
- Rotation: Mix theory-heavy days with problem-set days to avoid fatigue
Paper VI: Indian Economy — Data & Policy Playbook
Make a compact “India Data Deck” for the latest two years:
- Growth, inflation, unemployment range
- Fiscal deficit, debt, tax buoyancy
- BoP: CAD/surplus, reserves level, exchange rate band
- Agriculture: MSP trends, irrigation, FPOs
- Industry: PLI coverage, logistics costs, electricity access
- Services: IT exports, tourism, finance deepening
- Social: poverty estimates, health/education outcomes
- Climate: targets, renewable share, carbon intensity
In answers, quote directionally correct numbers (no fake precision). Tie theory to schemes, committees, and reforms, indicating trade-offs.
The Final 90-Day Sprint
| Window | Focus |
|---|---|
| T-90 to T-61 | Finish residual topics; daily mixed problem sets; start FL mocks (1/week) |
| T-60 to T-31 | Two FL mocks/week; compress notes; PYQ rewrites under time |
| T-30 to T-7 | Three FL mocks/week; only small fixes; protect sleep |
| Last week | Light revision; formula/diagram decks; essay/précis polish |
Interview: Dossier, Depth & Demeanor
- Dossier prep: UG/PG specializations, dissertation, internships—expect probing.
- Policy debates: inflation vs growth, deficit rules, trade strategy, labor markets.
- Communication: concise, neutral tone; acknowledge uncertainty; propose evaluation metrics.
- Mock boards: 3–4 rounds; record and self-review for jargon, filler words, and posture.
Common Mistakes & Fixes
- Too many books, few revisions: Freeze sources; aim 3–4 cycles.
- Ignoring diagrams/math: Draw clean, labelled figures; derive key results briefly.
- No econometrics interpretation: Practice “explain like a policy memo.”
- Indian Economy without data: Keep a 2-page data deck handy.
- Skipping English/GS: These add buffer marks; practice weekly.
Daily & Weekly Checklists
Daily (Mon–Fri)
- 2.5–3 hrs core theory (rotate Micro/Macro/Public/Intl)
- 60–90 min problem set (econometrics or macro numericals)
- 30–45 min Indian Economy notes + data refresh
- 30 min English (précis/essay) or GS quick review
Weekend
- One full-length/sectional test + deep analysis
- Revise the week’s error log and compress to flash notes
FAQs
How many hours per day are ideal?
6–8 focused hours on weekdays and 8–9 on weekends are sufficient if you keep problem-set discipline and weekly mocks.
What if I’m weak in math?
Prioritize intuition. Re-derive a few central results repeatedly; keep a one-page formula sheet per chapter and solve small, varied numericals daily.
Do I need to memorize numbers?
Remember orders of magnitude and direction (rising/falling). Quote ranges with year tags; avoid unverifiable precision.
