BharatNotes Four weeks, six days a week, 90 minutes a day. Week 1: PYQs to diagnose weakness. Week 2: Maths + reasoning fundamentals. Week 3: Speed comprehension + 2 mocks. Week 4: 4 mocks + error-log revision. Total: ~60 hours of focused work, enough to clear 66 if your basics are decent.
The 30-day crash plan
This plan assumes you have ~25 days from start, six effective days per week, and 90 minutes per day. With Prelims 2026 on 24 May 2026, this plan ideally starts around 24 April 2026.
Week 1 — Diagnose (Days 1–7)
- Day 1: CSAT 2024 PYQ, full 2 hours. Score honestly.
- Day 2: Analyse — list every wrong/skipped question. Tag as concept gap, trap, or speed issue.
- Days 3–5: Solve CSAT 2022 and 2023 papers — the toughest. Build a personal error log spreadsheet.
- Days 6–7: Solve CSAT 2025 PYQ (most recent benchmark) and analyse.
Expected baseline range: 45–65 net. Below 45 means you need 60 days, not 30.
Week 2 — Rebuild Maths + Reasoning (Days 8–14)
| Day | Topic | Source |
|---|---|---|
| 8 | Number System (LCM, HCF, divisibility, remainders) | NCERT 8–10; Mrunal aptitude |
| 9 | Percentages, profit-loss | Mrunal; R.S. Aggarwal |
| 10 | Ratios, averages | NCERT 9–10 |
| 11 | Time-speed-distance, time-work | Mrunal |
| 12 | Mensuration, probability basics | NCERT 10 |
| 13 | Blood relations, directions, clocks, calendars | Disha CSAT |
| 14 | Series, coding-decoding, syllogisms, DS | Disha CSAT |
Week 3 — Comprehension + Mocks (Days 15–21)
- Days 15–18: Solve 4 comprehension passages daily (16 questions). Drill the "stay inside the passage" rule. Read 1 Hindu editorial + 1 IE op-ed daily.
- Day 19: Full mock #1 (14:30–16:30 timing). Analyse.
- Day 20: Light revision; error log.
- Day 21: Full mock #2. Analyse.
Week 4 — Simulation + Polish (Days 22–30)
- Day 22: Mock #3.
- Day 24: Mock #4.
- Day 26: Mock #5.
- Day 28: Re-solve CSAT 2023 PYQ as the final tough benchmark.
- Days 29–30: Revise error log only. No fresh papers. Sleep early.
Daily routine (90 min)
| Block | Minutes | Activity |
|---|---|---|
| 1 | 15 | Concept review of one micro-topic |
| 2 | 45 | Practice problems (15–20) |
| 3 | 30 | Error-log update + light RC reading |
What to skip in a crash month
- Don't chase decision-making and ethics-passages — they're rarely tested now.
- Don't read R.S. Aggarwal cover-to-cover — pick only PYQ-mapped chapters.
- Don't take 5 mock series — pick one, finish 5 mocks.
- Don't watch new YouTube playlists — stick to one trusted source (Mrunal recommended for non-maths).
Realistic outcome
With a decent reading habit and average maths comfort, this 30-day plan gets most aspirants to 75–90 marks — comfortably across the 66 line. Aspirants starting from a 35–45 baseline may end at 65–75 — qualifying but tight. Those starting under 35 should aim for 60 days, not 30.
Worked scenario — crash-plan trajectory
| Stage | Net score | Notes |
|---|---|---|
| Day 1 (CSAT 2024 diagnostic) | 55 | Mostly RC + 4 maths sitters |
| Day 19 (Mock #1) | 62 | After 1 week of maths |
| Day 21 (Mock #2) | 68 | Crossed qualifying for first time |
| Day 24 (Mock #4) | 75 | Stable above qualifying |
| Day 28 (CSAT 2023 redo) | 70 | Tough paper, still qualifies |
| Prelims day | 77–82 | Conservative real-day estimate |
The trajectory works because the syllabus is finite and the crash plan is honest about what to skip.
Topper voice
Shubham Kumar (AIR 1, CSE 2020): "In the last month, I didn't pick new topics. I revised the same PYQs and the same chapter notes. Comfort with familiar material beats novelty under exam stress."
Mentor's note
Thirty days is enough — but only if the first week is honest. Diagnostic mocks must reflect real exam conditions: 2-hour timer, no breaks, no looking up answers. Self-deception in week 1 produces overconfidence in week 4.
