Methodology
1️⃣ Read each subject with PYQs in mind. Identify frequently asked areas.
2️⃣ Solve PYQs right after completing a subject to reinforce conceptual clarity.
3️⃣ Attempt one mock test per subject after completion to test retention.
4️⃣ Revise Current Affairs (CA) of each month for a week (June 2024 onwards).
5️⃣ CSAT practice: Solve 40 PYQs daily, topic-wise by prioritizing the topics.
Phase 2 (6 Apr – 5 May 2025): Exam Simulation & Intensive Revision
The 30 Days Subject-Wise Timeline
Objective
✅ Shift from subject-wise PYQs to year-wise PYQs for an exam-like experience.
✅ Strengthen retention with short notes for quick revision.
✅ Increase CSAT practice and attempt full-length mock tests (FLTs).
Strategy
1️⃣ Revise all subjects again within a compressed 30-day timeline.
2️⃣ Solve PYQs year-wise instead of subject-wise to improve exam temperament.
3️⃣ Create one-page summaries of PYQs for last-minute revision.
4️⃣ Quick Current Affairs revision: Allocate 4 days for each month’s CA (June 2024 – present).
5️⃣ CSAT practice: Solve 40 PYQs daily, year-wise & in a time-bound manner.
6️⃣ Attempt GS FLTs every 2-3 days to simulate exam conditions.
7️⃣ Attempt one CSAT paper every Sunday for structured CSAT practice.
Phase 3 (6 May – 23 May 2025): Final Streamlined Revision
Objective
✅ Refined revision, focusing only on high-yield topics.
✅ No more mock tests—just structured revision of syllabus + PYQs.
Key Actions
1️⃣ Final revision of all subjects (fewer days per subject depending on strengths & weaknesses).
2️⃣ Revise PYQs using the one-page notes created in Phase 2.
3️⃣ Current Affairs revision: Allocate 2 days per month for each month’s CA.
4️⃣ CSAT: Work on difficult areas & revise necessary formulae/concepts + comprehension PYQs for logical reasoning refinement.
