BharatNotes A 45-day plan compresses the 60-day structure: 28 days for one thorough revision pass plus one fast pass, 12 days for mock-test optimisation, 5 days for taper. The defining choice is whether to attempt full second pass of all seven subjects or only the four weakest — most aspirants benefit from the latter. Run 6-8 full-length mocks in the mock phase, with forensic analysis. Current affairs runs as a daily 30-minute parallel thread. The compression is real, so attempt discipline (80-90 questions max) must be locked in from Day 1 of mocks.
The 45-day Prelims plan is the most practically useful window for the modal serious aspirant — long enough to accomplish meaningful revision but short enough that scope discipline is non-negotiable. The structure adapts the 60-day plan by compressing the revision pass and concentrating the mock-analysis phase. Here is the day-by-day blueprint.
Days 1-21 (Revision Pass 1): three days each across seven subjects, identical to the 60-day plan's Pass 1 but with slightly tighter daily targets. Day 1-3 Polity (Laxmikanth full revision plus 30 PYQs), Day 4-6 Modern History (Spectrum 1857-1947 plus 30 PYQs), Day 7-9 Geography (NCERTs 11-12, G. C. Leong selected chapters, daily 15-min atlas, plus 30 PYQs), Day 10-12 Economy (Ramesh Singh basics, Budget 2026, Economic Survey 2025-26, plus 30 PYQs), Day 13-15 Environment (Shankar IAS, conventions, schemes, plus 30 PYQs), Day 16-18 Science and Tech (current affairs compilation, basic NCERT, plus 25 PYQs), Day 19-21 Ancient/Medieval/Art and Culture (Nitin Singhania selected, NCERT 'An Introduction to Indian Art', plus 25 PYQs).
Days 22-28 (Revision Pass 2 — Selective): unlike the 60-day plan, you do NOT revise all seven subjects again. Identify your four weakest subjects from Pass 1's PYQ accuracy and revise only those, one day each (Days 22-25). The remaining three days (Day 26-28) are dedicated to revising the three strongest subjects from your hand-written notes only — quick retrieval, not re-reading. This selective second-pass is the most important discipline of the 45-day plan; aspirants who try to redo all seven subjects in 14 days end up with shallow coverage everywhere.
Days 29-40 (Mock-Test Optimisation): 6-8 full-length GS Paper-I mocks at 2-day cadence (mock on Day 29, analyse on Day 30, mock on Day 31, and so on). Use two different test series to vary framing style. Each mock followed by forensic categorisation of every wrong answer (Unknown / Silly / Risk-management). After mock 3 or 4, your attempt count should stabilise in the 80-90 range; if you are still attempting 95+, force yourself down because the negative-marking math is unforgiving for over-attempters. Include 2 CSAT mocks during this phase (Day 33 and Day 38 work well) to keep qualifying-threshold competence fresh.
Days 41-45 (Taper): Day 41-42, weak-area consolidation from mock-test patterns (the three topics that produced the most Category A errors). Day 43, visual revision (60-80 image cards) plus consolidated lists (Ramsar sites, tiger reserves, biosphere reserves, schemes in news, Padma 2025-26, classical dances). Day 44, light revision of hand-written notes only plus one-page OMR exam-day protocol re-read. Day 45 (exam-eve), rest, no new content, confirm logistics (admit card, photo ID, black ball-point pens, water, route).
Current affairs parallel thread: 30 minutes daily throughout the 45 days, using one monthly magazine series across the 15-month window. Switch to weekly compilations only in Days 38-45 (final ten days) for the very latest items.
The topper precedent: Anudeep Durishetty's CSE 2017 preparation reportedly tightened to a roughly six-week disciplined window in the final stretch, with mocks at 2-day cadence and rigorous analysis. Shakti Dubey's repeated emphasis on 'select few standard books, revised many times' fits the 45-day structure precisely — the second pass is selective, but the books are not new. Shubham Kumar's advocacy of self-belief plus regular mock practice translates directly into the Day 29-40 phase's design.
A worked attempt-math: by Day 45, you should have done one full revision plus one selective revision (covering about 5000 pages of source material), 6-8 full-length mocks producing approximately 700-800 mock questions analysed in depth, and approximately 200 PYQs solved. The expected mock score trajectory is from a baseline of 65-75 in Day 29's first mock to 90-105 in Day 44's final review of past mocks, sitting comfortably above the CSE 2024 General cutoff of 87.98. An aspirant whose final mock scores cluster around 78-85 is in a 'borderline qualify' zone — the real exam will fluctuate around this band and the key in the actual exam is to attempt no more than 85 questions to maximise net score.
Three protective rules for the 45-day window. Rule 1: lock your source set on Day 1 — no new books, no new YouTube channels, no new compilations introduced after Day 1. The compression of 45 days makes source-switching catastrophic. Rule 2: protect Day 30-onwards mock cadence as sacred — if life intervenes (work, family), reduce other activities but never the mock+analysis cycle, because that is where most marks are recovered in the second half. Rule 3: do not chase a number — your target is not 'score 110 in mocks' but 'execute attempt discipline at 80-85 questions with 75 percent+ accuracy', which is the input that produces the output. Aspirants who fixate on a target mock score before reaching it tend to over-attempt to chase the number, which is precisely the failure mode the protocol is designed to prevent.
Finally, a closing reframing: a 45-day window is not 'less time' than a 60-day window in any meaningful sense — it is a different mode. The 60-day window allows for one luxury of broad coverage; the 45-day window forces precise targeting. Aspirants who embrace the targeting often perform better in the real exam than those who used the extra fortnight to dilute their focus across more material. The discipline of less, executed precisely, is the through-line of every topper account from Shakti Dubey to Aditya Srivastava — and the 45-day plan is the format that enforces it.
