📌 UPSC Prelims Strategy

Step 1: Understand the Syllabus Thoroughly

• Print out the UPSC syllabus and keep it with you while studying.
• This avoids wasting time on irrelevant topics.

Step 2: Build Strong Foundation

• Start with NCERTs (Class 6–12) for History, Geography, Polity, Economy, and Science.
• Make short notes (or highlight important points).

Step 3: Move to Standard Books

• After NCERTs, go for advanced books (listed below).
• Focus on conceptual clarity rather than mugging.

Step 4: Current Affairs

• Read The Hindu or Indian Express daily.
• Refer to Monthly Current Affairs Compilations (Vision IAS / Insights IAS / ForumIAS).
• Revise monthly magazines, don’t try to read too many sources.

Step 5: Practice & Revision

• Practice Previous Year Question Papers (PYQs) (last 10 years).
• Attempt mock tests (at least 40–50 before Prelims).
• Revise multiple times (at least 3 rounds).

Step 6: CSAT Preparation

• Don’t ignore CSAT – many fail here.
• Practice comprehension, reasoning, and basic maths (10th standard level).
• Do at least 10–15 CSAT papers before exam.

2. Solve 10 years’ PYQs – UPSC repeats patterns.
3. Mock tests – learn time management + elimination technique.
4. Limit sources – Multiple revisions of few books > reading too many.
5. Stay consistent – 6–8 hrs daily for 1 year is enough.
