Mission UPSC 2027 — Week-by-Week Study Plan
A free week-by-week UPSC CSE 2027 study plan from October 2026 to Prelims: integrated GS coverage, CSAT practice, revision cycles, current affairs and mock tests.
This plan takes you from October 2026 to Prelims 2027 in 33 weeks, the way most successful candidates study: Prelims-first, Mains-integrated. Each week covers a block of static syllabus; you read it once for understanding, then for Prelims facts, and you write one Mains answer from it.
How the plan works
- Phase 1 — Integrated coverage (Weeks 1–22): Polity, modern history, geography, economy, environment, culture, science and IR, in dependency order. CSAT practice twice a week throughout — do not leave it for the end.
- Phase 2 — Revision cycles (Weeks 23–29): subject-wise revision with the quick-revision sheets, weekly full-length mock tests, and two laps of current affairs.
- Phase 3 — Final sprint (Weeks 30–33): mock marathons, a weak-spot week, and a deliberate taper before the exam.
Every day: one Daily Challenge, 45 minutes of current affairs, and the week’s notes. That is the whole system.
